Wrong.

From rfc1958:

   To quote from [Saltzer], "The function in question can completely and
   correctly be implemented only with the knowledge and help of the
   application standing at the endpoints of the communication system.
   Therefore, providing that questioned function as a feature of the
   communication system itself is not possible. (Sometimes an incomplete
   version of the function provided by the communication system may be
   useful as a performance enhancement.")

There is no such argument.
