Well, then ... how would I do be able to do that with the current API ?

+1. I'm not sure I would prefer an adapter over a new decicated
db_entity = entity.cw_adapt_to('OrmEntity')
rset = db_entity.related('my_relation')
# or: entities = db_entity.my_relation
the kind of thing you're thinking of ?
This would remove ``related()`` from entity's API. It would probably be
a good thing per se but i fear it would be painful to write because
``related()`` is used __so often__ ...
