That'd be nice to cut down, but certainly not a blocker.

It's pretty easy. Once the defaults change is in it's probably worth
cutting a beta or release candidate to email to dev/users, and if
there's no blocking feedback you go ahead and push it out (basically
writing up the release notes on the wiki, cleaning up trac, tagging
the repository, making sure everything we care about on hudson is
still passing, uploading to pypi and the website (the sdist tarball),
emailing our lists and python-announce, re-building and updating the
pointer to the documentation, ...) If it goes on for a while it's
worth making/using a release branch on github.
