It's short unless you assume that development goes on in private
maintainer trees during hard freeze.  It's always happened at least for
the block layer, and probably for everything else.  About 400 commits in
2.5 were authored before the 2.4 release.

The main issue is that shorter cycles may mean fewer and bigger pull
requests.  It also means more awareness of conflicts is needed.  We
definitely lack the continuous integration infrastructure that is needed
for that.
