Just my two cents here:

>From my experience, making commit messages or inline notes slightly
clearer against the findings that Sashiko reported could simply help
it understand things better and mute most of the false positives.

Otherwise, the number of the findings is a bit scaring; reviewers
would have to go through the long list of findings to check whether
each of them fits into one of the false-positive categories :-/

Yea, that happens too. Usually I would add a line at the end of the
commit message "a subsequent change will do X", which could clarify.
