Banjo is the most requested. That's what my point was.
I agree ignoring the others is silly.
I didn't make up the Smash 4 narrative at all. We know for sure that characters were made impossible due to 3DS' limitations. If Sakurai is bent on keeping her part of a tag team(which is quite possible, as she's not exactly hard to make otherwise, especially as an Echo alone. Or even a semi in 4), it's an actual fact it would be impossible in the 3DS version. It's quite possible it's the actual situation. It seems silly to dismiss this as impossible. Especially when she's still not in Ultimate, despite being a potential Echo or "easy to add". This narrative fits exactly what he planned to do with her. It's a reasonable theory and something people should keep in mind. Especially if she's still not DLC. Like, it's possible he changes his mind, but it's pretty odd how he has yet to. But once again, we know he's stubborn.
Nothing to disagree or agree on. That's just a possibility and may actually be the case. She was cut because she couldn't work as a tag team character(the sole reason he gave). She has yet to be in, with both cases literally being games where a Tag Team wouldn't work out as is. Either base(Ultimate, due to taking a lot more time than anyone else and thus was lower priority) or as is(3DS, because a tag team was impossible in that game). The theory fully holds up at this point. It doesn't mean it's right, just that there's literally zero evidence of why she hasn't been in otherwise. It's literally the only thing that can hold her back. It isn't relevance. It isn't being a clone/echo, because she is perfectly doable as that. The only thing that fits what Sakurai ever spoke of is that he wants to stick with a specific way to have her, and it hasn't been an option yet. In fact, it may never work anyway, since it wasn't just Brawl itself or any limitations. His ideal gameplay for her may just be too hard to work with. Which is all the more reason to drop the idea and just move on. This isn't like with Ice Climbers who he worked hard to make work on the 3DS, and it still didn't work out. They were already preset in Smash with a clear design. At least they had a good reason to split Zelda/Sheik up(besides the fact they were used like separate characters, which means them being split up wouldn't do much). Diddy being split up is only because he was coming in before Dixie ever would. He still worked. Dixie didn't as he wanted her to. Why he considers Diddy fine separate but apparently doesn't consider Dixie separate is hard to say. It could be caring too much about the original game designs, where Dixie was always a tag team character. It could be he considers this the best mechanic to represent her. It could be he doesn't think she's a necessity.
BTW, Metroid only has 4 characters because of an Echo. It's effectively meant to be 3 but had enough time. Dark Samus had no plans to be included beyond an Echo at any point. Dixie did, so her not being in yet possibly relates to his intentional plan. But as I said, dismissing a legitimate point when we know Sakurai is stubborn is silly. It doesn't matter how great Tropical Freeze is, or that Dixie evolved as a character. That doesn't change much of anything. If it's suspicious why Dixie isn't in yet, then there's your reason. He wants her to have a mechanic. It's not hard to see him being stubborn enough to take this all the way till it's possible or he's no longer making Smash. Just a possibly that needs to be accepted at this point.
