I have assumed that submitted packages would need to meet a
standard of some sort - was that incorrect?

That is to be expected... and only the distro is really equipted to
handle these issues.

I'm not sure what you mean here.  The distributions are the ones doing
the packaging, the Python version of CPAN should supply all the bits
needed for the distros to perform that function.

Maybe we see "embracing" them a little differently.  I believe
providing everything they need to turn a Python module/package into
their standard format, using their packaging and QC tools, does them
more of a service than providing pre-built packages created by a third
party.  I'm not saying binary style packages shouldn't be supported,
just that the emphasis should be on portable (in that they can easily
be turned into a system's native pkg format) source packages.

That sounds like exactly what I was enquiring about - as long as the
distutils pkg provides enough info for every distro to create their
own pkg.

Agreed.  The submission should not be accepted if it does not contain
enough information to be packaged.
