I remember a (brief) discussion and at least one call for nominating
branches to preserve (I believe there was more than one call), which
included a list that the poster (Antoine? Djirkan?) was planning to keep
and the kinds of things he was planning to drop.  I think it happened on
python-dev rather than here, though.  (Since I didn't have any branches
at the time I didn't pay much attention to it.)  I'm pretty sure it
was mentioned again just pre-conversion, but I don't think any details
were given at that time.
