... which is fine for those other drivers because they don't share the
same bus. That is not the case here - we have two different classes
of drivers on the same bus.

I don't like a justification that just because other subsystems do
something in one particular way, that is the only way things should be
done. I think there is good reason to have the structure we have, and
thus there needs to be a good reason to change it.

Maybe Andrew has a different opinion, but I think we need a better
justification for this change.
