Python 2.1 is the "officially supported platform" for Zope, so 
you are right that we mean "everything on the trunk must _work_ 
under Python 2.1". 

There are some subpackages (ZODB, DocumentTemplate, others) that 
have a life and an identity outside of the whole of Zope, and it is 
possible that the maintainers may refine the general rule for those 
packages ("code in package xxx must work with both 1.5.x and 2.1").

Refinements (and enforcement) of the general rule are up to the 
maintainers of the independent sub-packages.
