I don't believe in this. Trying to deploy something by severely degrading 
the customer experience in the fail case is worse than just failing it 
completely.

It would be better to keep it at 300 ms (still significant penalty), but 
instead recommend the OS vendor to install some kind of heuristic to flag 
for the user somehow that their IPv6 connectivity is degraded, and offer 
to fault find it... or let's invent some kind of telemetry where these 
kinds of breakages can be reported to the OS vendor so they can contact 
the ISP and alert them to the breakage?

Also, we still have the problem with PMTU blackhole detection and 
mitigation. Why isn't this turned on more?
