I agree, but it doesn't stop at diagnostics. There's already
-fdelayed-template-parsing that accepts broken user-code without notice
and barfs on valid code (like template and constexpr combinations). And
it's also enabled by default even though for a lot of SDK headers a
forward declaration of IUnknown would be enough.
