If your filesystem is one of them, you can set "assume unchanged" bit to paths you have not changed to cause Git not to do this check. Note that setting this bit on a path does not mean Git will check the contents of the file to -see if it has changed -- it makes Git to omit any checking and +see if it has changed -- it means Git will skip any checking and assume it has *not* changed. When you make changes to working tree files, you have to explicitly tell Git about it by dropping "assume unchanged" bit, either before or after you modify them.
Doesn't this also need the caveat that it is _a promise by the user_ that they will not change the file, such that Git doesn't need to keep checking, and that occasionally Git will check, or may perform unexpected actions if the user has the wrong mental model.
