Actually the whole point of it is that it *doesn't* need any new
protocol messages. And that it *wraps* whatever is there, definitely
doesn't replace it. It should equally be wrapping whatever an
extension uses.

So while the base topic is not unrelated, I don't think there is any
overlap between these.
