Hmm. I guess we could add function pointers to the ObjectProperty
array in objectaddress.c. Then we could just search the array for the
catalog ID and call the associated function through the function
pointer, rather than having a switch in shdepReassignOwned(). Since
anyone adding a new object type ought to be looking at objectaddress.c
anyway, that would be one less place for people to forget to update.

However, I'm not 100% sure that's an improvement. Switches by object
type are probably not going to go away...
