Comment (by Simon Charette):
Doing this automatically and correctly is really tricky as #28477 proved
(think of annotations spanning multi-valued relationships, `values`
grouping by annotations before aggregation) so I'd be +1 on adding a way
to pass `count` or `total` to `Paginator` and a way to clear annotations
but we'd have to document that the later is not panacea.
