Comment (by akaariai):

 #10790 just went in, rebased branch available from
 https://github.com/akaariai/django/compare/ticket_16187_new

 The commit history is ugly... but the basic status is that the above
 branch does implement custom lookups in barckwards compatible way. The
 next steps would be to convert the GIS ORM to use the custom lookups, and
 then to try to implement things like `datefield__year__2000=1`.

 After that the big question is how exactly to handle backwards
 compatibility. Otherwise I don't see currently any major problems for this
 feature.
