> +Before closing the connection, a GOAWAY frame MAY be sent to allow the client to
+retry some requests.  Including the GOAWAY frame in the same packet as the QUIC
 CONNECTION_CLOSE frame improves the chances of the frame being received by
 clients.

I think you're right. Thinking some more, I think the phrasing could be read to say that inclusion improves the probability of delivery, which is odd. When actually what it is trying to articulate is that processing order has some importance. However, just because the data arrives at the same point in time doesn't mean much IMO, that GOAWAY frame could just as well be blocked by other stuff waiting to be restransmitted on the stream.
