> Larger change, but one solution to that might be permitting a RCID frame to retire ranges instead of a single CID.

@MikeBishop I'm not sure if there's a problem here that we need to solve. The DoS that I described only works if an endpoint sends RETIRE_CONNECTION_ID frames for CIDs that it hasn't received / doesn't remember any more. As long as you only retire CIDs that you're actually keeping track of (as the spec currently says), the DoS doesn't work.
