Yeah that's kind of what I was getting at here
Just seen this which makes a nice point:
I can't see this coming to any Mario Maker though. The variety of things in place seems like it would be out of scope as it's specific to this game, so wouldn't work on other art styles. Which I know they did a bit for the NSMB style but seems more extreme here? The art style alone would be nice, but then would feel a bit like a half-fulfilled promise.
