Keep in mind that originally the ONLY special permissions "thing" we had was rolsuper. Now we also have replication, maybe some others, and there's discussion of adding a special "backup role".

In other words, the situation is a lot more complex than it used to be. So if cleanup is done here, it would be best to try and account for this new stuff.
