That's not how characters are chosen though? I mean, we already know what really goes on. In almost every case, it was "this character or no one", but besides that, when someone is chosen for a specific reason, you aren't going to see anyone even considered unless they were in a very similar position. So yes, it was PP or someone who is not a hero/protagonist/main character. Like, full stop. I don't know where anyone gets the idea it was ever going to be anything else. That's just wishful and unrealistic thinking. It's clear at every point PP was not like the other surprise characters and had a unique caveat. If said caveat can't be applied to other considered options, then it was PP or Nothing. If it can be, then it was PP or something on a similar level of a less important character. That's just, well, how development works. We've seen this every single time. Characters are actually chosen in quite a vacuum. Ice Climbers, for instance, are a very specific retro choice, and the only other choices were other retro characters. Pokemon? The only ones who had a chance were pretty much iconic ones in every case up until 4, where a slot was set aside, repeated in Ultimate. Again, extremely specific.
And so on. While there's some leeway, that applies to a lot of series, but not every time. The ballot, for instance, gave a list of characters who were big enough as options, and even then, that only applied to most of base game. Steve/Alex were in talks for 2015, so they basically were not affecting BK getting in, which was due to the ballot. It wasn't one or the other. It was just one individually or nothing in both cases. Etc. The only one we almost got another character ideally could've been from ARMS, however, that would imply Nintendo didn't actually choose Min Min, but that was still the case. Sakurai didn't choose a single DLC character except PP, after all. What that also means is that Nintendo clearly has taken suggestions from others and looked towards Sakurai to figure out if the idea works. Since that's why he was hesitant on Min Min cause like most people, he wouldn't think she's the main character(there happens to be no main character in that series, though Spring Man would come close at one point), and they didn't care about using either of the mascots obviously. The only notable thing beyond that is the Guess The ARMS Game, but that was just a promotional thing, and it also wanted to show how there was never a main character in the end, as anyone could possibly be chosen(which either means they don't care about previous in-game roles like AT's, though we know Spirits didn't matter, or it means Sakurai didn't find that to matter that much, or both). The fact they actually said Spring Man was possibly playable among that list showed how little the AT thing mattered by Pass 2(which makes sense in context).
I won't go on, but the whole point is that after a while, and in most cases, it was "this character or nothing", and in rarer cases "this character or something in the same position". It's a general development thing to basically do what needs to be done, dwindle down the choices. Unlike fans, developers can't try to decide between tons of choices for one single slot. They have to whittle it down to make a coherent game and plan things. PP was a bonus character too, which is a massive deal. That means that already it had to stand out, and it sure did, being highly recognizable. However, as noted. Sakurai didn't want a hero/main character/protagonist anyway, so he went with an enemy mook. Why? Cause it was a completely stand out character to do the job he wanted. The fact it turned out as a real head turner also is proof of it doing its job, but beyond that, it also was a really good and unique moveset, and showed how little importance is even placed on "super defined character"(which to be even more fair, was already a thing with Mr. Game & Watch basically just being the entire list of Game & Watch undefined characters rolled into one, as their real definition was "animation". It doesn't help he's less defined than any Pokemon either, but you start to get on why these unique things stand out. Also, technically R.O.B. was not legitimately defined, till his own in-story in Brawl, anyway. I won't go on, but "characters are chosen in a vacuum" may not be the most accurate way to say it, but "this person or nothing" is highly common if not the most logical way they prefer to get a character selected.

Sorry, I wrote that wrong. My point was "I don't feel it's worth to keep replying to you about it since it's going nowhere, and I don't consider what you're saying to be ironclad enough."
...Plus, these are getting wall-of-texty(not intended), so I'd say that's a good point when it's no longer interesting to talk about this much. It might be for other users on other threads, but this one is even more public for all, not a defined topic as much, so.
(This is also be a clear point I'd rather move on, too. Mainly I won't be responding about it anymore. And yes, that also blatantly means "Please don't respond to me about it." as well... which should be obvious anyway)
