``FilteredRelation`` doesn't support:
* Conditions that span relational fields. For example::
>>> Restaurant.objects.annotate(
... pizzas_with_toppings_startswith_n=FilteredRelation(
... 'pizzas__toppings',
... condition=Q(pizzas__toppings__name__startswith='n'),
... ),
... )
Traceback (most recent call last):
...
ValueError: FilteredRelation's condition doesn't support nested relations (got 'pizzas__toppings__name__startswith').
* :meth:`.QuerySet.only` and :meth:`~.QuerySet.prefetch_related`.
* A :class:`~django.contrib.contenttypes.fields.GenericForeignKey`
inherited from a parent model.
