IMO: yes. If we want end-users to use a particular flag, we should expose it as a Driver flag. If we want to reserve the right to change or delete it, putting "experimental" in the name conveys that -- significantly more than telling users to spell the flag `-Xclang -foo` does.

There's a real underlying problem here that the name `-Xclang` seems like "clang-specific flag" not "unstable internal API don't depend on me" -- to everyone who is not a Clang Driver developer...
