Bernstein's rant shows its age. It kind of proves the reverse of what you are trying to state.
The text starts with a question that undermines the whole text: "does every node need direct Internet connection?". Today, with P2P traffic on the uprise, the answer is a striking Yes. If, even with the hurdles of poor performing NATs, there is market pressure for P2P protocols, it's absurdly obvious the Internet must be symmetrical, not server-client.
The text then goes on about the impossible transition plan for IPv6. It's now obvious that moving servers to dual-stack, then clients progressively onto IPv6 (through provider address-space exhaustion) is a sound plan. It's happening, and it's approaching the critical point. 2016 starts at 10% IPv6 traffic, will end at 25% IPv6 traffic. No sound company today will launch its services in IPv4 only and eschew 10%-25% of potential traffic.
