With their knowledge, user base and fame they have the oportunity to redefine jQuery v2 completely with the things learned from v1 and everybody would learn it and use it.
Dont let fear to change crush the will to improve and move on. On a major release, one has todo what it has to do.
The problem with branching off like that is that now you're suddenly faced with a fragmented community. The worst thing of which being that everything is written for the "old" branch. Then nobody wants to use the new branch because there are less batteries included.
When nobody wants to use the new version, no new batteries get added.
It becomes a self-fulfilling prophecy.
(Performance and compatibility improvements are always welcome, though.)
