This API *is* hierarchical registration. v2 will (hopefully) prove that
it can be done efficiently.
We also need hierarchical dispatch. Priorities are just a weak attempt
to emulate hierarchical dispatch but I don't think there's an
improvement over a single dispatch table.
Hierarchical dispatch is simpler. You just need a simple list at each bus.
I don't see a strong need to tie anything to qdev here FWIW.
