Yeah, especially given that I removed a deprecated method  
(beforeCommitHook), so its installation may tend to break running  
systems.  Maybe I should put it back, as systems will probably  
continue to "just work" even if they have this installed for any  
system that uses a recent Zope.

Yes.  ZODB's setup.py is polyglotic... it works if setuptools isn't  
installed.  I suspect it shouldn't continue to given that it now has  
an external egg dependency.
