Good debug logs have a value beyond software debugging by its developers - they are useful for ops too. More than a few times nginx and postfix debug logs allowed me to see how requests are processed and find a mistake which would be hard to spot just by looking at the config. Debug logs can be enabled for requests from configured IP even on a server with high load if traffic from the IP is low; rr I assume has no such option.
