I think what an endpoint is required to track are:
* active connection IDs
* sequence number of connection IDs that are being retired (but are yet to be acknowledged)

When receiving a NCID frame with RPT, an endpoint checks if there are any active CIDs below the RPT, and retires them. I do not think an endpoint has to track RPT, though admittedly, I haven't implement them (yet).
