dde2537fbb04ad78a673092a931b449245a2d6ae is the commit I was referring to,
we don't refer to commits or ticket numbers in docs though.
I think the existing documentation is clear enough that
`ExpressionWrapper` might be necessary in these cases, the only admonition
I would add, assuming we believe it might be valuable is a note in
[https://docs.djangoproject.com/en/5.0/releases/5.0/#miscellaneous the
miscellaneous section] of the 5.0 release notes mentioning that explicit
`ExpressionWrapper` wrapping might be necessary for integer field
arithmetic that can overflow while it wasn't the case in previous release
by referencing at the documentation mentioned in comment:2.
