From the thread I didn't see that the compiler side asked you not to do so.
And I disagree with the view. libc++ shouldn't *wait* for compilers, because
we don't dictate users' compiler choices. This change doesn't make libc++
worse to coming compilers, and makes libc++ better on existing compilers, so
what benefit we get by not approving this?
