So in general I would really appreciate a few words on *why* you're
doing things. I mean, I can read the patch and see what it does, but I
cannot divinate (esp. not without yet having read the rest of the
patches) why you're doing things.

This is esp. important for large series -- or series that do complicated
things -- or like this case: both!
