And it's not just the development that's already queued, there's tons
of patch series in developer trees that need to be rebased too. Doing
treewide stuff at -rc1 is as disruptive as any other time for
developers overall, it only optimizes the disruption in Linus repo.

The other reason I'm not too fond of doing treewide stuff as one huge
patch is that those cocci patches are perfect newbie fodder for their
first patch. Of course once a refactor has tappererd of it's good to
do one final push, but not always and consistently.
