Thinking about language features and core type this seems reasonable, but
with the standard library this seems less reasonable -- there's lots of
conservative changes to the standard library which aren't bug fixes, and the
more the standard library is out of sync between Python 2 and 3 the harder
maintaining software that works across those versions becomes.
Though one opportunity is to distribute modules from the standard library
under new names (e.g., unittest2), and at least in Python 2 you don't have
to do anything fancy or worry about the standard library has catching up to
the standard library forked module.
Library installers seem particularly apropos to this discussion, as everyone
seems excited to get them into the standard library and distributed with
Python, but with the current plan that will never happen with Python 2.
