> @@ -753,6 +753,12 @@ delivery of ACK frames is important for efficient loss recovery. Packets
 containing only ACK frames should therefore not be paced, to avoid delaying

+creates a packet burst that might cause short-term congestion and losses.
+Implementations MUST either use pacing or limit such bursts to minimum
