To the extent we can discourage the formation of the
one-big-group-to-rule-them-all by encouraging the formation of smaller groups, I
think it's a good idea.  But in reality, I think nothing needs to be done:
group-forming will always be a self-selecting process.

This just seems like a blindingly obvious antigoal to actually breaking apart
the software into more discrete bits using eggs.  Why not just stick with a huge
tarball release or one single egg if it all has to be versioned through time to
99% of its consumers as one giant collection of software treated as a unit?

Right.  No one except people who've already bought in to the notion of Zope
software as one huge pile will benefit from the lockstep centralized planning.
It won't gain Zope any new users; no different framework users will begin to use
Zope software as a result of this plan.  How is this different than the current
status quo?

It doesn't pose a problem.  It's just business as usual.

When components are not treated as one giant pile, and it's expected that you
should be able to use pieces of the pile selectively without buying in to some
unrelated software, dependency management becomes far more brutal and realistic.
