Well, enforcing it strictly never really worked all that well in
practice, since you don't necessarily want to have a complex driver
implementation while hashing out the API, and the API fundamentally has
to come first.

So in a sense it comes down to trust, and that people will actually
follow up with implementations. And yeah, plans can change and you end
up not really supporting everything that was defined ... that's life, I
guess.

But the mode here seems to be that there's not even any _intent_ to do
that?

I guess we could hash out the API, review the patches, and then _not_
apply them until a driver is ready? So the first round of reviews would
still come with API only, but once that settles we don't actually merge
it immediately, unlike normally where we merge a patch we've reviewed?
And then if whoever did it lost interest, we already have a reviewed
version for anyone else who might need it?

Cool :)
