> An endpoint is allowed to drop the packet protection keys when entering the
closing period ({{draining}}) and send a packet containing a CONNECTION_CLOSE in

creating an unwitting amplification attack, such endpoints MUST reduce the
frequency with which it sends packets containing a CONNECTION_CLOSE frame.  To
