PS. Though I now realize that the maximum about of bytes that each server would ping-pong is limited to 3x the size of the datagram that the attacker sends.

So it might be possible to call this a non-issue, though the number of UDP packets that the servers would send might be less concerning (it would be like 30 UDP packets, assuming that the packets containing CONNECTION_CLOSE would be around 100 bytes each).
