Right, we definitely need 2.10. And after 2.10 is released we could do
point releases for regressions *and* serious bugs.

Yes. Would you do that in a 3.0 branch or in the trunk? If we wait for
2.10 before any work on 3.0 starts I guess we could the cleanup
directly in trunk.

Agreed. How about asking developers to document (in a wiki page) all
the API changes that their commits to the 3.0 branch (or trunk) imply.
This would help us keep track with the work being done, and it would
help with the 2to3 migration notes we will provide when 3.0 is
released.
