That looks about right to me; why don't you just submit that as a patch ?

These are automated emails sent from a bot. I just look them over and
hit send. A lot of the time they are for patches which aren't applied
to a git tree yet.

But in this case, sure I can send an email. I looked at this one a bit
closely because it's a new warning that was only introduced last week.
