AFAICT this isn't being done because it is slow and was deemed unnecessary. However, it should be such a rare operation that speed doesn't matter, and not doing it results in two problems: 1) It is theoretically possible to remove an aux device from one pool and attach it to another, then lose power. When power is restored, both pools woul d think that they own the aux device. 2) Removal of the aux device doesn't send any useful sysevents to userland.
