It seems a bad idea to put this extra info in a distutils standard,
the binary release version have been managed outside of distutils for
a long time and it works perfect.

Allowing an arbitrary file to to be read via the egg-metadata API
seems a much better solution, then any packager using that facility
can completely decide what format to use and freely encode more
information without hiting new distutils limitations (like your
pinning).  Of course there's nothing wrong with pypm keeping it's
sqlite db for it's own data either, other binary package managers keep
that info outside too.
