There was a private method add_to_query() for objects in add_q(). Using this it was possible for the objects to add themselves to the query's where/having condition. This capability was removed from 1.6 as part of ORM refactorings.
I have seen at least half a dozen complaints/questions about this removal. So, clearly this feature was used more than I anticipated. It will be relatively easy to add similar capability to 1.6, though the API needs to change a little. This will be around 5 lines of code change with practically no risk of regressions. So, I am going to add the capability back unless somebody objects.
The API will likely be add_to_query(query, used_aliases, where_node) where it was previously add_to_query(query, used_aliases). The where_node addition is needed due to other changes in the ORM.
