Comment (by mdentremont):
Potentially?
My thinking was that #22841 is for passing in a queryset which will not be
revaluated, where I want the re-evaluation to a avoid stale content, I
just want the prefetch to be respected to avoid too many queries.
Also it took us a ton of investigation to determine why the prefetch
wasn't performed, it is not obvious at all. If I pass a queryset along, I
expect that it will be used entirely, not just certain pieces of it.
