just keep the names and have the delegation pointers moved to a new place
(which already might be responsible for something else).
For example look at DNS - there is no problem in having the same people
and servers caring for the zones COM and ORG.

Sure, delegation of long-term responsebileties only makes sense if the
delegation can be moved (since people and organizations get born and die).
One probably should also care for the case that something goes away
completely (even if only for theoretic completeness of concept:-).
