Another solution is to mark it static, but also add
__attribute__((unused)) to shut the compiler up, so that you don't cause
build failures, but also don't cause reviewers to wonder who is using
it.  Then when it finally gets used, a patch to remove the attribute is
easier to see than a patch adding static.
