Personally, I would say that our default should be that __has_cpp_attribute isn't required to have special implications for macro expansion. Of course anyone is free to make the case that it should, but I'd be inclined to put the burden of proof on the proposer (or supporters). We could make it implementation-defined, to leave clang an option for not changing their implementation. But, like Richard, I don't feel strongly about that one way or the other.
