+An immediate close can be used after an application protocol has arranged to
+close a connection.  This might be after the application protocols negotiates a
+graceful shutdown.  The application protocol exchanges whatever messages that
+are needed to cause both endpoints to agree to close the connection, after which
+the application requests that the connection be closed.  When the application
+closes the connection, a CONNECTION_CLOSE frame with an appropriate error code
+will be used to signal closure.
+
+The closing and draining connection states exist to ensure that connections
+close cleanly and that delayed or reordered packets are properly discarded.
+These states SHOULD persist for at least three times the current Probe Timeout
+(PTO) interval as defined in {{QUIC-RECOVERY}}.
+
+Disposing of connection state prior to the exiting the closing or draining state
+could cause delayed or reordered packets to generate an unnecessary stateless

Sure, the new text works I think.
