Sounds good to me, except that I think it's worth explicitly raising on www-style that we're planning to ship this, since the spec for it isn't yet in (or near) CR. (The bug says the editors believe the feature is stable enough to ship, but that's worth raising more widely before we ship it.) -David -- 𝄞 L.
