Yeah! This is much cleaner. I need to add ordering to some model
relations (i.e. represent all related values as an ordered list, where
relations can be shifted up & down) to the M2M field, it looks like it
would fit much easier using a manager & concrete Model subclass than
being restricted to a field.

I don't vote often, but +lots.
