We can transition to a new driver using the same binding but we should be keeping the old binding. If we're moving the binding document around and/or transitioning to YAML that needs to be done explicitly rather than adding a new document for the same compatible. > As long as that one doesn't get removed, I have nothing against this driver > here.
