Now look at the root-servers:

The IPv6 is gone.
On my own boxes I had problems to reach sites that had both
IPv6 and IPv4 addresses for one and the same server until
I unplucked the IPv6 stack.
My problem was there were nonconnected IPv6 islands that
could not see each other.

Given the above, I think there is no myth.. !
That's because the 'v6 network' is broken enough that putting AAAA
records on sites that need to be well reachable is a bad idea.
For example, due mainly to Vista's 6to4 tunnelling stuff (based on
researching a random sample of users), I'd lose about 4% of visitors
to my web-sites if I were to turn on AAAA records.
Has anyone who was using AAAA records for a site turned them off due to
reachability problems?
