I am not a native English speaker, so if new_id is better than
superseded_by than I vote for new_id.

Regarding the added semantics I am very cautious. Because it will be
impossible to model all semantics of ID meaning changes that possibly
exist.
I would prefer to stick with the simplest possible solution and that is
provide a dirt simple replacement link for a deleted (for whatever
reason) object.
