The idea of PEP 376 we are working on is to have a unique unified
standard for distributions
installed in site-packages, instead of the current situation where we
have many installation formats.
(Distutils pre-Python 2.5, Distutils post-Python2.5, Setuptools
self-contained Eggs, ..)
because it makes it simple to provide APIs to query what's installed,
and ways to uninstall things.
That's what I would call the "Missing APIs" to make Distutils a
package manager, or at least a basis for package
Having an egg installer/uninstaller that works with Setuptools-like
self-contained eggs sounds like
a package manager system on its own and yet another format.
But as far as we went in the discussions for PEP 376, it seemed like a
first step would be to work with a single
installation format and provides all APIs for it, then to think about
having other formats and ways to query them
in a second move.
That's why I don't think its the right time to add a bdist_egg command
in Distutils, until PEP 376 is
fully defined (and maybe extended to support several format).
