To reiterate: currently, this emits a warning, which should not happen. As an analogue: it is akin to raising `Wreserved-identifier` from _within_ `<vector>` when consumers write `#include <vector>`.

I don't think we did. You're building a part of libc++ in a way we don't support AFAICT. I don't know too much about modules, but I don't think you're ever supposed to compile the modules manually unless you're doing some low level shenanigans, at which point IMO it's totally fair to require you to pass funky flags.
