I feel that even though people outside it's fandom aren't talking about it much, NASB did have some significant yet subtle effects on Smash discussion - for one thing it certainly feels like it destigmatised wavedashing a slight bit with how simple it made the technique, but as well as that I've seen side characters getting in over protags discussed a lot more after Helga; Nigel; Reptar; only two Turtles; e.t.c. (Pyra and Mythra were probably a bigger factor in this, especially since they came before NASB's reveal, but at the very least they have a main character for their series)
