Risk mitigation;  we have significant support requirements for deployed 
systems built around CVS for both 2.6- and 2.7-based sites, whereas the 
head and Zope3 have no such inertia.  We don't know enough about the 
migration process to have any confidence that existing history / 
branches, etc., won't be somehow messed up, which makes it prudent to 
plan the migration around the already-unstable bits.

The only downside is having to generate patch files, rather than 
allowing CVS / SVN to merge fixes.  On the otherhand, merging is one of 
the things which are really easy to mess up;  I found myself generating 
them, and editing them, to get things to apply cleanly during the 
"crack-a-Zope" effort in December / January.
