Often lost in the 'debate' about V6 adoption is that for a 100% native IPv6
experience to work, there are multiple other components that have nothing
to do with the network that ALSO have to work correctly. Any issues with
these are likely going to cause fallback to v4.

It's very difficult to know how much v4 traffic to a website COULD have
worked just fine on v6, but didn't, and why it didn't.
