This article that "begs to differ" is inventing IPv6 all over again. It just refuses to call itself so.
I quote from the top comment:
>So you have to ship new code to every 'network element' to support IPv4x. Just like with IPv6.
and
>So you have to update DNS to create new resource record types [...] Just like with IPv6.
and
>You need to update socket APIs to hold new data structures for longer addresses so your app can tell the kernel to send packets to the new addresses. Just like with IPv6.
The point is less about the technology proposed, but the point that there could be an interoperable version of a next generation IP and IPv4.
IPv6 did the braindead thing and completely threw out the idea of transition and interoperability for a clean slate. We're paying for it many decades later.
Also, rather than regurgitate a comment, perhaps you should read the article, because that comment misunderstands what is being proposed and thus completely missing the point.

Yes, it's IPv6. The thing you linked basically took one of the interoperability methods of v6 and described it in weird terms.
You don't do dual stack with v6 either, unless you want to -- you can do the incremental rollout and tangible relief thing with v6 just fine. (But it turns out most people do want to do dual stack.)
