The binding document as it stands only has one compatible, there's no
existing problem with it other than the YAML conversion.  If we're
adding something new that requires a fallback we should be explicit
about that rather than have something that's actively misleading where
previously things were clear.  I don't mind if we add the compatible to
the driver or document the requirement for the fallback but we should do
one of the two.
