Why? What does it it buy us?  Multiple local addresses for protocols
which (unlike IP) dont allow multiple addreses on a single interface?
DIfferent MTUs on difference instances of a local-loopback interface?

If you're sure you're not just looking for a bikeshed to spraypaint
your name on, maybe you could update lo(4) to document the change and
the new usage(s) that it enables?
