Comment (by Josh Smeaton):
(I lost the original comment I wrote here so here's a condensed version).
Using a ForeignKey as the output_field is an interesting idea that I
hadn't considered, and would solve any backward compatibility issues. I
don't know what the difficulty would be, but F fields already have access
to the query to add necessary joins. I doubt foreign key fields are added
to joins right yet, but __underscore relationships do add joins to the
query. The next hard thing would be reconstructing the object.
All of this sounds doable though.
