Comment:
I quickly checked the related fields for .create() support and both
reverse foreign key and m2m field has support for create.
I think my current approach would be to add bulk_create() support for
reverse foreign key (as it is somewhat easy to do so), and just raise
!NotImplemented from m2m.bulk_create(). Fixing the m2m bulk_create would
require support for returning the primary key value from bulk_insert to
create the links, and that support is not currently available (and is not
going to be available in the foreseeable future).
In addition generic relations need a check for this, too.
