Comment:
`filter()` and `exclude()` are unsupported but doesn't raise an error yet.
As [https://docs.djangoproject.com/en/stable/ref/models/querysets/#union
per the documentation], ''"only LIMIT, OFFSET, COUNT(*), ORDER BY, and
specifying columns (i.e. slicing, count(), order_by(), and
values()/values_list()) are allowed on the resulting QuerySet."''.
