You know, I once had a proposal..... Uh, never mind :)

We had that once. We got rid of it because it made deployment harder.
With slugs you can just drop in an extra file without having to change
one. That makes automated installation easy.

Heh, that's actually a funny example because Debian has actually been
using modular config files for quite some time now (not only for
Apache). Especially module includes, module configurations and virtual
sites all rest in individual config files. Small tools (a2enmod,
a2ensite) help manage the files, though manual management isn't too hard
So, seems like not only are we the first ones to come up with a setup
like that, it's also used by a large

You should "know" which ones you want in your instance anyways. I rather
have a very, very slim "standard" set of packages and make everything
else optional than provide everything else by default.
If the software home ZCML file (which essentially is
zope.app/configure.zcml) includes too much, it's a pain to disable
things you don't like. It's trivial with package-includes.

It's been giving us a lot of pain in Zope 2. I don't think anyone
seriously wants to go back. We *can* have a standardized location (by
convention), e.g. $INSTANCE_HOME/lib/python, but let's not make it a
