Comment (by Carsten Fuchs):
Replying to [comment:2 Peter Law]:
> My use-case was similar to the one mentioned here, however I was loading
full models (with a similar count annotation) and not any form of
`.values()`.
> […]
> What I've seen of the reasoning for the deprecation appears to be
related specifically to `.values()` queries, and then really to cases
where that is used to create a grouping ''of the main queried table''
(where the user is probably aware that that's what they're doing). However
the behaviour change impacts ''all'' querysets (including those which
return full models) and the behaviour here is ''not'' intending to create
a grouping of things on the main table, but rather of a related table for
the purposes of counting (where the user is unlikely to be aware that a
group-by is the result).
I concur with Peter: The place where this is currently documented, namely
as linked by Mariusz in section
[https://docs.djangoproject.com/en/5.2/topics/db/aggregation/#interaction-
with-order-by Interaction with order_by()], is a subsection of
[https://docs.djangoproject.com/en/5.2/topics/db/aggregation/#values
values()], suggesting that this is relevant only in the context when
`values()` and `order_by()` are used together. For me, too, it was not
obvious that this would apply to broader cases without `values()` as well.
Therefore, I would like to request that the documentation is clarified
about this.
