Thanks for that write-up - I learned quite a few things I didn't know,
even though I was actually around for 2.5 development (the fact I had
less of a vested interest in packaging issues then probably made a big
difference, too).

Yeah, I think Tarek had the right idea with working through the slow
painful process of reaching consensus from the bottom up, feature by
feature - we just got impatient and tried to skip to the end without
working through the rest of the list.

It's worth reflecting on the progress we've made so far, and looking
ahead to see what else remains

In the standard library for 3.3:
- native namespace packages (PEP 420)
- native venv support (PEP 405)

Packaging tool interoperability standards as Accepted PEPs (may still
require further tweaks):
- updated PyPI metadata standard (PEP 345)
- PyPI enforced orderable dist versioning standard (PEP 386)
- common dist installation database format (PEP 376)

As I noted earlier in the thread, it would be good to see the
components of distutils2/packaging aimed at this interoperability
level split out as a separate utility library that can more easily be
shared between projects (distmeta was my suggested name for such a
PyPI project)

Other components where python-dev has a role to play as an
interoperability clearing house:

- improved command and compiler extension API

Other components where python-dev has a role to play in smoothing the
entry of beginners into the Python ecosystem:
- a package installer shipped with Python to reduce bootstrapping issues
    - a pypi client for the standard library
    - dependency graph builder
- reduced boilerplate in package definition (setup.cfg should help there)

Other components where standard library inclusion is a "nice-to-have"
but not critical:
- most of the other convenience features in setuptools

Cheers,
Nick.
