Comment (by Simon Charette):
As pointed out by others support for filter against window functions would
allow `prefetch_related_objects` to use `Rank(partition_by)` to support
this feature.
If someone wants to give a shot at solving this particular issue before
#28333 is resolved it should be doable by using a combination of
`Queryset.raw` and `Query.compile` combinations.
