Per the docs ( http://docs.djangoproject.com/en/dev/topics/db/models/#extra-fields-on-many-to-many-relationships), yes you must use symmetrical=False when defining a many-to-many relationship from a model to itself, using an intermediary model. That's a pretty clear statement and I don't see any escape clause. What extra work, exactly, does that mean for you? A concrete example may people understand what problem this introduces for you.
