The goal is to provide a first version by the time 2.7 is out.

Understand that the distutils2 project is happening outside the stdlib
at this time,
so you will have to install it on the top of Python in any case.
Last, its release cycle will be shorter until it gets back in the
stdlib, that will make it easy
to add features.

Interesting, can you start a new thread on distutils-SIG for this
part, so we can discuss it there ?
