Oh. Not if we infer that from .h or .hxx, because then a lot of existing use cases will break. I guess that does call for a new predicate, then.

I've only been able to find warn_using_directive_in_header that does a similar check, only to realize that it's not 100% correct. It uses SourceMgr.isInMainFile which is not right if you pass a header file directly, no warning is generated in that case.
