I think that there should be absolutely no change whatsoever, for two reasons:
 - the release is in a few weeks, it is too late to change much. The
whole datetime issue happened because the change came too late, I
would hope that we avoid the same mistake.
 - there was an agreement that with py3k support, nothing would be
changed in a backward incompatible way, that's also the official
python policy for py3k transition.

Deprecations are fine, though,
