In #36606, this case was optimized, but it was also agreed we can
deprecate it. Using `values_list(flat=True)` doesn’t clearly declare which
fields to fetch, and while it happens to select the PK due to field
ordering, that’s unclear. It's also a bit counterintuitive, compared to
calls without `flat=True`, which select *all* fields.
