IMO versions do nothing except complexify the code.  I believe it's an
official Zope Corp position to discourage them for new projects.  Yet
Jeremy Hylton seems to think that they are somehow useful and has
carefully preserved them in ZODB 4 (== Zope 3).  If it were up to me,
they would have been gone, with a big helping of YAGNI!
