The "application context" vs. "window context" UI dichotomy is certainly interesting; I think both mechanisms can be fine and implemented well or poorly. Ubuntu's was always extremely poor. Unless the toolkit and, to some extent, the applications are designed for that use-case, trying to hack their menus to appear at the top when they were expected to be part of the window is just a disaster. It's unfortunate that we just don't have the resources to make a sane desktop-level application menu on the desktop-linux stack, even with all the might of Ubuntu. But that seems to be the case, so I'm glad they're moving to something more feasible. Even if it's a little disappointing.
