(In reply to Roman Krotov from comment #54)
[[nodiscard]] is in C23, so we can expect that attribute to be adopted where
people intend that behavior (warning suppressible by cast to void) as opposed
to the nonportable [[gnu::warn_unused_result]] (warning not suppressible by
cast to void). So this problem will resolve itself, over time.
