I can empathize and see the motivation behind the intention but question the feasibility. If it has taken this long to partially implement ipv6 and other IP implementations like ipv10 [1] are suggested as workarounds, then making the existing 127/8 routable would be a herculean task that I can not even imagine being accomplished in the foreseeable future. There are hundreds of thousands of hardware and software stacks that make heavy use of the loopback network and not just 127.0.0.1. Some modern operating systems do have flags registry/sysctl that enable routing 127/8 with the primary use being the likes of GRE tunnels, name spaces for pods/containers/openstack, etc.. The software stacks on top of that will require changes, configurations will require changes, network gear will require changes, all the ISP's would have to agree to this. This may seem simpler than ipv6 but I would suggest it is not at all. I can think of simpler solutions but nobody would like the fallout from them.
