This is our "legacy" case. That is, clients that do 0-RTT today without this new mechanism. The cost to sending 4NN is that it causes the client to use generic 400 processing, which probably doesn't include a retry. That's not the end of the world, though it probably means that the response is a terminal failure as opposed to a recoverable one.
