The proposal is about shrinking the reserved loopback range from 127.0.0.0/8 to 127.0.0.0/16. Everything from 127.1 to 127.255 would then become ordinary IPv4 addresses.
Can't see this being useful. There are so many devices and so much software with 127.0.0.0/8 baked in that I suspect an address in the proposed range would be less routable (overall) than an IPv6-only endpoint, and remain so for years, even if it became official.
Wait what? Are you saying that they’re going to allocate the loopback range as v4 addresses?
