I agree and think we should document the minimum release required for
building CURRENT.  At the very least we shouldn't continue to suggest
that 6.0-RELEASE is sufficient, if we're not going to address the
bootstrapping issue.

(I noticed that UPDATING also still has a section "To upgrade in-place
from 5.x-stable to current," and many obsolete entries, and so could
do with a good cleanup.)

All that said, I'd really like to be able to continue building head on
RELENG_6.  (In my case I have a rather fast RELENG_6 box so I have been
doing my pre-commit testing there.)  Do the changes we're discussing
here involve anything that makes that difficult?
