The relevance of TFA is that this only works if the initiating party is still connected, and to make matters worse there is no ERR_SOCKET_CLOSED returned by most chat clients if that party got distracted before seeing the ACK. Then minutes or hours later they get back "hey sorry, missed your reply, ${QUERY}"

when they could have just included `${QUERY}` in the initial send, or at least `framing(${QUERY})`.
