This was the plan for packaging vs distutils2, and I'll be proposing
something similar for distlib, too.

It can be a little tricky to manage at times, but you can do truly
experimental features in the PyPI version first with a warning that
they're experimental (e.g the various incarnations
contextlib.ExitStack went through when I first added it to
contextlib2), while bug fixes and features you're more confident about
can go directly into hg.python.org and then be published early through
the downstream project.

Cheers,
Nick.
