As discussed before your tolerance for risk in stable is *far* higher
than mine, if there's any value in doing this at all it's probably
within what would get taken but that doesn't mean that it's something
that it's sensible to highlight as an important fix like tagging for
stable does.  It's extremely unclear that it fits the severity criteria
that are supposed to be being applied to stable, though obviously the
documentation doesn't fit the actual practice these days.
