Streams after receiving GOAWAY

I'm about to deliberately violate the letter of a MUST NOT because I believe it's overly strict. "Receivers of a GOAWAY frame MUST NOT open additional streams on the connection..." When my server wants to close a connection it sends a GOAWAY with last stream id set to a value somewhat higher than anything it has received. It then keeps the connection until the reported last id is reached or enough time goes by. When the client gets a GOAWAY it will immediately start establishing a new connection, continue issuing new requests up to the reported last id, and close the old connection when it either has a new connection or has used all the reported streams. The goal is to avoid suspending requests in a high volume server to server environment while waiting for new connections. I don't see how it conflicts with any conforming implementation, am I missing something? Thanks, Antonio
