to v4-240+, which will surely only benefit a few.

I am told by people who have inside knowledge that one of the issues they are facing in deploying IPv6 is that an IPv6 stack + IPv4 stack have a larger memory footprint that IPv4 alone in devices that have essentially zero memory for code left (in fact, they're designed that way). Fixing devices so that they can accept 240/4 is a software fix that can be done with a binary patch and no additional memory. And there are a _lot_ of these devices.
