Even if we forego these blanket statements you provided no basis for, now somehow 'M isn't optimized and A has seen more work' does not imply M is inferior to A... Well, if that doesn't mean M is inferior it can only mean A is so hopeless that even though it's being heavily worked on, it cannot rise above unoptimized status. Dunno, must be my English.
Well, good news ! Meego and Qt already do that.
Then I can say - that final version will never-ever be released, except for maybe low-q knockoffs. Every vendor will do their optimizations. That's why you can't say 'ready'. MeeGo 1.1 might not have functionality/service X, or might sluggish because of driver Y, but that does not mean products based on it don't have that sorted out (just like you count the services Google provides towards Android features even though they are not part of the core OS features).
