What is an implementation? The application running over the tunnel? You refer to "An encapsulating protocol" in the sentence before the bullet points, is this what you mean?
For a tunnel protocol it is the tunnel protocol implementation that needs either implicitly or explicitly indicate or signal that it will use zero checksum for a particular flow or ports.
That was a point that I made concerning the text. Are you planning to add text to the draft(s) to indicate configuration and implicit signalling are OK?
