As asked by auvipy, this is a thread to discuss the implementation for this ticket.

The idea in the proposed implementation was: When a natural key is available for a GenericForeignKey, this one is used with the field name "content_object" rather than "object_id".

As Tim Graham pointed out, that makes the core library (which contains fixtures serializers) aware of the generic foreign keys which are in the contrib library.

In the github PR, i proposed an approach where we declare dependencies between fields (eg object_id depends on content_type) and use these deps to serialize/deserialize in the good order and benefit from natural keys if they exist.
