It looks like there's no model that fits what I'd like to do. IMO, the
user should be able to specify the PK in DB-generated mode when either
the field is exposed, or the PK is set through the ObjectID map. Cayenne
should not disregard user-made decisions: it isn't Cayenne's
responsibility to enforce PK integrity.

You can specify the key yourself easily:
http://cayenne.apache.org/doc/primary-key-generation.html
But I can't see how you can guarantee you will not get collisions
between your two schemes. Maybe better to keep the old key in a separate
field for reference purposes.
