Comment:
I think you're misunderstanding the `annotate` vs `aggregate` features of
the ORM.
Annotations of aggregate functions have no choices but to group by the
queryset's model to provide a result for each rows. If you want to perform
an aggregation over filtered rows without grouping you'll want to use
`aggregate` instead.
