If that's what the owners of the driver want to do then I've no problem
with supporting that approach. But I very much think that we should aim
to have drivers integrated into the Nova tree as they mature so we can
gate on them. Or if not in the tree then at least have a system that
supports developing in a way that makes gating on them possible without
the downside pains of not being able to change internal APIs easily.
