My issues with FLUDD are purely functional. Like, Cape is "outdated" too, that powerup has literally never returned since Super Mario World. I just don't really think FLUDD adds anything valuable to Mario's kit, and doesn't feel like a more very characteristic of him. It just happens that on top of that, it's a very specific reference to an unorthodox Mario game so it feels more expendable as a result.
At a certain point I accepted that Mario's specials were probably deliberately chosen for him to mirror the shoto layout in Smash 64, lol. We could discuss whether or not that feels outdated nowadays, but I never questioned Mario having an uppercut too much since it does pay homage to his most famous pose.If anything Super Jump Punch is strange because it's... Just an uppercut.
