I believe that was proposed before IPv6.
That being said, we should take the time to understand why IPv4 is still hanging around when IPv6 has been around since before most people got internet access. What is really holding IPv6 back?
Everything in v6 was for a good reason, but it was targeting now-outdated use cases. Separately, there's no good migration path from v4. They should've kept the v4 address blocks in v6, and following the natural consequences of that, it'd be way easier to migrate. But they didn't do this with v6 because they were trying to solve the address fragmentation issue upfront, which again had valid reasoning but in hindsight wasn't the right move.
