Just to be clear, I certainly wasn't criticising those who use fallback mode, or trying to imply "they" (you) were all just whining for no reason. I think they still have a lot of work to do. When I upgraded from 3.4 to 3.6, I was pretty annoyed because out of the eight or so extensions that I used, all but one stopped working. Luckily, the extensions that I used were all upgraded within several weeks, but it's still a major issue. I think it's pretty clear from the extensions site that this is still a work in progress. That's part of the reason I really like this announcement, though - exactly as you've said, it looks like they're going down the path of "official set of well-maintained extensions", which I think is the right choice. I guess that GNOME 3 isn't entirely ready for everyone yet, but the future that I see for it is pretty awesome. For me, personally, it already far surpasses GNOME 2, and I think it still has a lot of potential that it hasn't utilized. (I can't really comment on multiple monitor setups, though. I just have a laptop.)
