Yup, indeed it did.
I assumed this was *only* enabling subsystems and that the
framework/API was already accepted.
So the advice I'd give to Tomeu when sending full enablement
patch-sets i.e. ones which provide the framework/API *and* enable
subsystems in the same set, is to send the entire set to everyone, so
we can see what the aim of the set is and how to deal with it.
