If the Fixes tag, reference a commit that is missing in specific
stable branch then obviously the fix is not suitable.
Hence the stable piece than be ignored + alongside a reply to the
patch that it will not be in $stable_branch because $reason.

Some customers may use non-stable branch, hence having track of which
fixes they need is a smart move.
