Exposing TCP framing to the application at the receiver side does not make much sense. On the other hand I'm somewhat puzzled by the fact that TLS specifications explicitly discourage exposing TLS record boundaries to applications which is exactly the case of turtles framed in turtles all the way down. Edit: we can all collectively make fun of telco protocols that are HDLC-in-HDLC all the way down, but such things usually do framing only on the outermost layer.
