IMHO, you can't say "unlikely" or "maybe". GCC bootstraps itself with
-Werror, so if even one such instance occurs in it's own source, then
we have to update the format checker to accept it or we'll get a
warning-error which will halt bootstrap.
OTOH, if we go through the effort to make the format checker aware of
these, then you don't have to discourage using it. You can feel free
to use it exactly as much as you feel is necessary.
