I recognize these AT arguments can be tiring and tend to go in circles a bit, so if you don't feel compelled to respond then that is alright.
I am going to respond here, however, since it is a topic I am particularly invested in.
I just don't see Nintendo carving out this really weird lane for AT characters getting potentially promoted where their AT is effectively turned off when they're being controlled by a player. Sure they could but will they really consider doing that? Nintendo is a bunch of suits, I can barely flatter the idea of them having this level of imagination, especially for a game they seemingly begrudgingly do somewhat or at least have a very complicated relationship with.
Now, see, from my perspective it is equally weird for them to quit on making a character they really want playable just because of the minor, auxiliary representation that already exists. If it is weird for you to think of turning off the AT for certain battles, then note that there are other possible solutions, including just straight-up allowing the AT and PC to appear on the battlefield simultaneously.
Even if your view of Nintendo is so negative, one would think that corporate moneymaking urges would override the presence of an AT if the AT character was the one they really think would make money as DLC. Even if you don't think the current ATs are DLC moneymakers, that doesn't mean that in principle an AT'd character in the future couldn't be that or couldn't become that sometime after being AT'd.
Ultimately it seems like we interpret Nintendo as an organization very differently.
Probably, yeah. I mean, I definitely don't agree with everything they do and at times have been dismayed by certain "business realities." I also write a lot on here pushing back against promotional characters and such, so it's not all sunshine and roses. But they're human beings liable to both praise and criticism like everyone else.
They had to have known Byleth wasn't going to go well hence they dumped them at the end of a widely celebrated Fighters' Pass composed of otherwise completely new third-party franchises.
In their eyes, any character they add is a good addition to the game that they want people to be excited about. The fact that the people clamoring for a continuation of the third party flooding with every single pick set their expectations the way they did was not Nintendo's fault, nor was it likely Nintendo's anticipation. From Nintendo's perspective, FE:TH was still a "new world" added to Smash with a lot of fans, especially among the general Nintendo audience who bought copies of TH like hot cakes. As much as I criticize Nintendo's handling of third parties in Ultimate's DLC, I wouldn't go so far as to say Nintendo simply stopped thinking that some of their own IPs couldn't make profitable and exciting additions as well.
I'm sorry but what aspect of Waluigi's potential in Smash is missing from basically leading the entire pack of the ATs?
Among the things that
could possibly have been factors against Waluigi:
side-character syndrome;
lack of mainline appearances;
lack of obvious auxiliary content to comprise a full fighter pack;
only allotting so many slots to 1P chars and deciding to use those on characters more directly promoting a specific Switch game;
and, yes, moveset potentially since most of the DLC characters had more complex and/or gimmicky movesets, which I don't necessarily imagine for Waluigi.
Note that I actually like Waluigi and don't necessarily agree with all of those as reasons to exclude him, but from their perspective any or all could have been issues.
Also saying Waluigi is the top AT to consider and the one that'd likely have been chosen to be promoted if it was to happen doesn't ignore the merits of the other ATs but yeah saying he leads the pack does separate him from the rest and it's true.
It's not just that you're claiming Waluigi would have been their top AT choice. Even if he was, I don't think the gap was so large as you claim, and not so large that him not getting in allows us to make a blanket statement about the chances of all other ATs going forward.
Should they have actually said "Oh except Springman because he's an AT" in the actual direct or a Sakurai column? They're a business and Sakurai represents that business whenever he's doing anything Smash related. They're never gonna take time to speak directly to the concerns of Smash speculators or highlight their criteria for Smash inclusion like that. Them saying nothing of the sort has no material impact on the fact that Springman was still skipped over and it was very likely because he was an AT already.
No, I don't think they would have gone out of their way to say Spring Man was ineligible during the tease, if that was the case. That I can concede. They didn't just quietly exclude him from the tease while saying nothing, though, which they could have done also. Maybe his inclusion in the tease is only a minor point in his favor, but it still represents one of many potential opportunities for them to mention the AT as an issue where they did not do so.
I just see the "everyone is the main character" bit to be an obvious deflection away from the issue. The reason for this deflection is to keep their cards closer to their chest and in doing so remain in the more advantageous position when doing anything from negotiating the characters all the way to the eventual reveal/release of said characters.
Obvious? No, definitely not obvious. Maybe you are more cynical about Nintendo as a company than I am, but here I am saying their claim is a plausible thing that could have happened even if I disagree with it. Remember that it's not just the "everyone is a main character" bit, which could, yes, in theory just be them further buttering up the real reasoning. It's IMO more importantly that the ARMS director wanted Min Min to be the rep. The "everyone is a main character" bit might not have even been a necessary factor given the other one.
First and foremost Min-Min is more popular than the rest of the ARMS cast.
Again, I think this is just a further illustration of how characters' circumstances can change during the time from the ATs being chosen to the time of the DLC roster being chosen. Min Min's popularity might not have been as emergent or noticeable to them at the time of the ATs being chosen; her status within the ARMS fandom has only been heightened by recent years and so it's possible she simply surpassed SM in the time since SM was chosen as the AT to represent ARMS. So, again, Min Min being popular just presents a further possible scenario other than the AT being an issue. And that goes back to my point that there's so many good explanations for Min Min being chosen that the AT being an issue seems more and more wildly speculative to me.

my problem with them getting promoted in the same game as DLC is that it would (IMO) waste dev time going back and accomodating for them, in which case they might as well have been playable in the base game if Sakurai was able to do so.
But again, the resources spent on the ATs in base represent a sunk cost by the time they decide the DLC, which is almost certainly budgeted separately from all the items in the base game, anyway. Their philosophy has always been to make the base game as good as it possibly can and not "save" or purposefully exclude items for later DLC. Doing the best they can for each and every character in that base game that they want to be as good as possible from the start is a primary motivating factor for auxiliary forms of representation like ATs, Trophies, etc. Circumstances for characters can change dramatically between base roster decision time and DLC decision time; previously unforeseen events and circumstances like new releases or ballooning popularities can change a character's priority ranking.
It is not a waste to do the best you can for a character only to later take the opportunity to improve upon that previous representation. Companies make newer, better versions of existing products all the time and it is not a waste. In this case the original AT could potentially still serve its original purpose in the game alongside the new PC, which makes it even more of a non-issue.
