A tunnel is defined by its ability to transfer packets between ingress and egress. How the tunnel decides what loss rate is sufficient is its decision. A tunnel has no way to know "path" at all; that concept doesn't exist in the Internet except using LSR or SSR. What it does know is loss rate and whether that correlates to packet properties - flow IDs, ports (if visible), packet length, etc. Any of those can be a consideration in deciding when to declare a tunnel down. Short of sending every bit combination repeatedly and using positive acknowledgement, an ingress can't know whether the packet contents are causing loss. However, since I don't hear anyone else on this list raising this red herring, it doesn't seem critical to even explain in detail as to why it need not be addressed in this doc.
