And furthermore, it is my understanding that in RRL no queries are ever
discarded. Only the response is throttled.

disappointed me with this characterization of RRL:
There is a conversation thread that says that resolvers should
implement response rate limiting (RRL), and silently discard
repetitive queries that exceed some locally configured threshold.
that wording did not leap out at me at the time, but, is factually wrong.
RRL is on the server side not the resolver side.
