This question is based on your that belief that this protocol will "escape" onto the public Internet, that browsers and other clients used by individuals will feel forced to implement it, and that clients will then be forced to enable the extension in order to get through middleboxes that would filter traffic based on whether or not the extension is present in the ClientHello. I've already explained why I believe that scenario will never happen, and so no I do not agree that it is a "fundamental change." The idea of a client extension was added based on feedback at the Prague meeting in order to help prevent the protocol from being used over the public Internet, by preventing the protocol from being used without the client's knowledge. Obviously you believe that the method being proposed to address one concern introduces another concern. I do not share those concerns for the reasons that I've already stated. I don't plan to comment on this issue any further, and doing so would just be repeating myself, thus just adding to the noise.

It signals on the wire to any observer that the client and server agree to this. TLS never attempted to control what the client or server could do. But it never put any such signal on the wire. This is an important and fundamental change, and it allows traffic to be categorized and handled differently. > > Do you agree with that? >
