I'm attempting to use NSManagedObject validateForDelete in order to
provide timely feedback to delete actions by users. But the
relationship delete rules don't seem to be getting applied as I would
expect.

-validateForDelete: is intended as a potential delegate hook for subclasses of NSManagedObject. It's designed to be called from within -save: to perform any customized validation you might need on deleted objects.

It's not intended to double as -canDelete or -isDeleteable. It will produce something vaguely to that effect if you call - processPendingChanges first, although that's not its purpose.
