It just needs a cherry on top in the form of an AT getting promoted as DLC.
In that case, AT needs effort and cost, while spirits are merely PNGs. Cannot say Nintendo really lost anything when they decided to pick the spirit character.
Relunctantly, if we were in the old days when Smash has to do trophy models for characters like Stanley from DK series, they at least mattered.
I'm aware that people sometimes focus on the wrong thing. We want the theories to be debunked so that NIntendo can be more cautious and considertate when they pick the fighters and contents. Winning or losing the argument isn't the main reason why the thoeries need to (or no need to) be debunked.
Min Min is a win win because she is
deserving. If FP6 was Metal Mario and NIntendo merrily announced they debunk the spirit deconfirm theory, I don't think fans would be as hyped as now.
Similiarly, I don't think Lucas can be directly compared with Min Min's case. One is a returnee and one is a new creation. I would disagree if someone say "we already have Lucas case so Min Min isn't new".
