Comment:
It's 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."''. See
#27995 for a ticket to raise a helpful message about this.
