Not much discussion there; adding my comments...

An alternative is to simply do away with it and have the server respond as soon as it wants with the 401 status - with flow control the client won't get too far ahead of the server, and with streams we don't have to deal with the expense of closing the connection and bringing a new one up (something that you need to do with HTTP/1.1 if Expect isn't supported by the server...)

Either way we should say something about it to give guidance/recommendations on HTTP/1.1 solutions that are adding support for HTTP/2.0...
