All the components you mentioned other than the switch to LESS and the animations used by hovercards for instance were actually created over a year ago before the start of the mediawiki.ui work. I can talk further with the developers about the performance issue, but yes, it's only part of the issue. As I said before I don't think it fits stylistically with the direction of the mediawiki.ui

I find that slightly contradictory, when every new UX feature/extension has made heavy use of the newest CSS trickery, including transparency, animations, fade-ins, rounded corners and drop shadows. Everything that pops up on Wikipedia has them: Echo notification, watchlist notifications, ULS popups and everything else I can't think of.
With that in mind, the performance argument is a misnomer; older [define?] browsers tend not to support shadows anyway, so no problem there. The code is also *not* more complicated when done in LESS.
You just don't like the style, that is fine. It was intended to be a local CSS framework for templates anyway.
