If an NTP client is already misbehaving and/or misconfigured to the point where it's considered "abusive", what are the chances the client will do The Right Thing(TM) when it receives a "kiss of death" ("kod") packet from the NTP server?
Enable KOD, by all means, but you may also consider putting in some (high) per-IP rate limiting for 123/UDP in your firewall rules as a backup plan (for if/when clients ignore kod).
