Comment (by Étienne Beaulé):

 Must disagree, felixxm. Neither `StdDev` nor `Variance` is in scope for
 this task as using the `DISTINCT` keyword on these aggregates is not as
 widely supported by SQL backends (such as Oracle). Supporting these would
 require more involved work. Some discussion was had about using
 `check_expression_support()` in
 [https://github.com/django/django/pull/9174 GH9174] but was dropped.
