IMO, a major disadvantage of CVS is that it is mostly "file"
oriented.  In many (most) cases, multiple files evolve together.
It isn't correct to use a particular version file without using
compatible versions of other files.  CVS has a feature to tag
collections of files to represent a configuration of files with 
compatible versions, but you don't get to provide meta-data for tags
and tags are an advanced feature that seems somewhat "tacked on".

Zope, on the other hand, is transaction oriented.  Zope tracks meta-data
for transactions, not individual objects.  This is a much saner approach,

It will impact this issue eventually.  I can't say how soon.
