Really? Because last time I checked your speculation revolved around Sakurai having a choice when the man himself said otherwise. The reason why I'm quick to believe him over what you're speculating about (which is still baseless, mind you, because your examples never fit within the time period of the Smash Ultimate DLC), is because he's the guy working behind the scenes and the only official source of information we use on a regular basis. Meanwhile, as far as I see it, you're someone who is trying to combat his inconvenient statements with baseless speculation. Rules change, sure. But in this case, these aren't rules. We've known for a long time Nintendo was making these choices, that information has not been contradicted and as a result, it's valid.
Okay keeping this as short as I possibly can:
After seeing gameplay from both Iceclimbers and Urban champion, you are simply reaching with that argument. And the example was far removed from the topic at hand.
Sakurai mentioned the Japanese age rating bored in the untranslated version of that same direct when talking about Mai, as expressed
In THIS article. So it's safe to assume that Shulk and ZSS were safe and Mai took it a step too far in accordance to a 3rd party ratings board.
All of my statements and assumptions have been based around what I've read about in the past. I've brought up recent and relevant information to back all of my sentiments. You, who has yet to give me any proper evidence to show that Sakurai would've been lying or untrustworthy when he said he didn't want to add anymore FE characters, are in no position to criticize how I conduct my arguments here.
