You mean like, having a distutils1 project without setup.py ?

At the last sprint, we ended up thinking that it would be better to
have a setup.py that work only with distutils, and let people using
setup.cfg for d2 (and if needed, hooks)

This is way simpler for people because we can tell them: leave your
setup.py as it is so you are compatible with installers like pip and
easy_install for the time being, and add stuff in your .cfg. That way,
they don't have to throw distutils2 code in the mix in setup.py, and
be confused with all the subtle differences. And they'll follow that
way the "no-setup.py" philosophy
