My take is that you really can't get reliably-ish v6 outside of Far East 
areas (excluding some regions with e.g. acedemic networks and some single 
companies).

That's not enough as lots of traffic does not go inside these regions.

The point of no return is when _global_ v6 works, not just within
(isolated) islands + some points of interconnections.

Do you consider AAAA records tried first (in some regions like US/Europe) 
a problem that needs solving?
