Yes, that's basically all I was talking about.
And one should be able to exist in an IPv6 world without having to know what
the packet headers mean, just as I currently exist in a state of blissful
ignorance about most of the bits of the IPv4 header.
However, being able to exist with an IPv6-only machine on the internet and
fetch pages from an IPv4-only host without any network address translation,
proxying or other network shenanigans is, AFAICS, completely impossible. If
that's what 'backward compatible' means, then I'm afraid Mr Austin is out of luck.

Or, as Martijn says, has IPv6 stuff in the box but not enabled - you need an
extra license for that functionality, matey.

And to the same effect.
