_Does_ it fall outside the RFC? Section 3.4 covers the establishment of 
(cleartext) HTTP/2 connections via prior knowledge, and seems to 
describe exactly this use case:

I agree that the method of establishing this prior knowledge is 
undefined, but the h2-direct mode seems to be within the RFC's scope. If 
you agree, I'd suggest removing that line from the docs.
