--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> ---
The patch I posted for the related pr88993 also relaxes this warning for printf
and fprintf:  https://gcc.gnu.org/ml/gcc-patches/2019-02/msg00224.html

Like in the case of pr88993, the warning is by design and (in my view) makes
sense for sprintf but it's not very useful for the other functions where very
little code worries about exceeding these limits (or even cares about the
functions failing as they can for many other reasons).
