rjmccall added a comment. Is Marshall arguing that the standard doesn't allow compilers to warn about failing to use these function results prior to C++17? Because I don't think that's true; warnings are thoroughly non-normative.
If libc++ wants to allow its users to opt out of these warnings just for libc++ functions, that's fine (although unusual), but it seems to me that that ought to be an explicit opt-out that's independent of language version.
