        Return an iterable of models.

        By default, the following models aren't included:

        - auto-created models for many-to-many relations without
          an explicit intermediate table,
        - models that have been swapped out.

        Set the corresponding keyword argument to True to include such models.
        Keyword arguments aren't documented; they're a private API.
