26127	ReverseManyToOneDescriptor doesn't respect use_for_related_fields attribute	Robert Robinson	nobody	"The other two descriptors respect the flag and will use the _base_manager if the manager has use_for_related_fields set to false.  The ReverseManyToOneDescriptor always uses the _default_manager regardless of whether it is supposed to or not.

{{{
def related_manager_cls(self):
        return create_reverse_many_to_one_manager(
            self.rel.related_model._default_manager.__class__,
            self.rel,
        )
}}}

Or am I misunderstanding: 

  If this attribute is set on the default manager for a model (only the default manager is considered in these situations), Django will use that class whenever it needs to automatically create a manager for the class. Otherwise, it will use django.db.models.Manager.
