I'll try anything once!

Fair warning, I think this is going to massively complicate things. 

Either we're going to be left with a situation where child-driver
maintainers are scrabbling around looking for previous versions for the
MFD pull-request or contributors being forced to wait a full cycle for
their dependencies to arrive in the maintainer's base.

I'm not sure why simply providing your Ack when you're happy with the
driver and forgetting about the set until the pull-request arrives, like
we've been doing for nearly a decade now, isn't working for you anymore
but I'm mostly sure this method will be a regression.
