I'm not convinced there isn't a more direct way to represent
the relevant relationships.

Either way, we don't have enough experience with this stuff
yet to know what works well and what doesn't (at least, I
don't, and I haven't seen any evidence that others do); so
I'd prefer to keep this in per-device bindings for now; it
should be there anyhow, but once we do have experience with
it we could do some recommendation.
