The main focus was about how the bad edits could be repaired.
Another element of repairing bad edits briefly touched on in the above thread is spotting bad edits reliably/quickly.
To this end: could subscribing to edited entities be automated (with opt-out available) such that editing an entity results in an auto-addition to a auto-generated Subscription category?
Artists that an Editor adds to the database seem to end up in the personal “Artist Subscriptions” already.
