We usually don't care if there would be a warning inside system headers, we only check user-code. It's okay if internal implementation would give a warning - it is usually filtered out.

I've checked `common_type` and it works fine https://godbolt.org/z/9WjKse9fd. Maybe variadic templates were forgotten when the check was originally implemented. Could you add a test-case for it then and put back `tuple` and `variant`. In limitation, should be only nested namespaces left.
