Just to put this into perspective, this is not some life-and-death  
issue for me at this point, more a clarification issue. It wasn't  
clear to me how limited the target audience for CMF 1.6 really will be.

I think this brings up the need for a slightly more formalized  
planning and release process. Given the requisite backing by at least  
the main developers (meaning their agreement that they would actually  
use such a thing) I'd like to set up a release plan page on zope.org  
that explains a bit more what the goals for each major release are  
and which contains timing information as well. The Plone roadmap page  
at http://plone.org/roadmap (plone.org seems down currently) does a  
nice job in that regard.

By the way, my technical problem of satisfying dependencies on  
GenericSetup introduced by us switching to PAS without breaking a  
production Plone 2.1 site have been solved by simply using  
GenericSetup from the 1.6 branch and keeping everything else at CMF  
1.5.4.
