PS. Or, if we are to consider H3 tunnels that does not do reframing as something within the scope of the specification, I think we need to have something like #3303.

Consider the case of a H3-H3 intermediary that parses the request, and binds HTTP requests to different origins, transmitting the *response* as-is without dealing with frames. Such a tunnel would work as expected, assuming that QPACK dynamic table is not used.

In this type of design, a stream-level error (i.e. abrupt termination of a stream) does not indicate a connection-level error. Therefore, we need to state that.
