Why? POSIX only specifies what happens when you use options specified by
POSIX. Since status=noinfo is an extension, the mere use of it implies
that you are intentionally asking for extended behavior not covered by
POSIX, at which point we can silence whatever we want without violating
POSIX. A strictly conforming app will never uses status=noinfo, and will
never know the difference.
