This meme needs to die. IPv4 is the problem - since it contains no
provision for variable length addresses, there is mathematically no
such thing as a backwards-compatible design for extended addresses.
We didn't invent the dual stack mechanism because we liked it, but
because (regardless of all design details of IPv6) there was mathematically
no alternative.
