Please use the official cover-letter format (--cover-letter).

It would have been nice to at least find a diff stat here.

...

Do we really need to coordinate this series cross-subsystem?

Can we first apply the API, then have each of the subsystems adapted

If the latter is the case, is this set bisectable?
