I would think so. This maps to what we have done with networks + ports in
quantum v1. Maybe some of the melange authors can comment here as well.

Thanks!
It seems that this is not the case with the base v2 support - for
example the deletion of a network:

def delete_network(self, context, id):
with context.session.begin():
network = self._get_network(context, id)

# TODO(anyone) Delegation?
ports_qry = context.session.query(models_v2.Port)
ports_qry.filter_by(network_id=id).delete()

subnets_qry = context.session.query(models_v2.Subnet)
subnets_qry.filter_by(network_id=id).delete()

context.session.delete(network)

I think that I now understand what "Delegation?" means. :)
