I don't think we have well established rules for whole-tree cleanups
like this. In the past, several cleanup series got lost.

It will take ages to get every subsystem maintainer to review the
patches. Most likely, since they are quite systematic, there isn't
much to say and it is easy to miss something that has some hidden
ramifications. Perhaps whole-tree cleanups should require at least 2
reviewers to bypass the subsytem maintainer review? But my past
experience with this kind of exercice doesn't encourage me, and
probably I am not the only one.
