Yeah, the problem is that MATE is doing it in completely the wrong way. They've got the classic UI, but the crap code - whereas Gnome 3 has the much improved code that they're not using. They started by trying to continue the old Gnome 2 code, instead of immediately porting the small number of Gnome2-only modules (the panel, the old control panel) to 3. By doing the latter, they'd be in the position of sharing most of their code with upstream Gnome, maintaining only their own small set of packages. As-is, they've inherited *everything* that was in Gnome 2, even the stuff that still exists in 3.
