Alternatively, you can scope the pragma and declarations appropriately and then we don't need to add a new attribute. Is there a reason that wouldn't work for you? (This attribute would be interesting to consider if we added a feature flag like `-fdiagnose-discarded-results` where the default is as-if everything was declared `nodiscard` and then you could mark the APIs with `[[clang::discardable]]` for the few whose results don't matter. However, that's also a much bigger feature because system headers are a challenge.)
