So I had stumbled on the same fact about a year ago and after some discussion on this list I deleted about 8000 empty/orphaned relations. It seems all except a handful of those 8000 relations had indeed been left in the not-deleted state by mistake. There were a couple (<5) that had still been referenced from the wiki, rather than from inside the database through other relations. I got a couple of e-mails months later asking about those relations and undeleted them, it would probably be a good idea to check for references in the wiki beforehand this time. I don't think it makes sense to create such empty relations before any members are added to them because it's quite likely someone else is going to create a duplicate, but I don't have a strong opinion and being in the losing position as an author of an automated edit I didn't want to argue with the creators of these relations.
