IIRC this idea has come up at least once before, and maybe more (not sure
where - perhaps in v6ops?). I don't oppose it - in fact, I think it's a
good idea - but since the previous attempt(s) never came to anything, I
assume there was no consensus that this is useful.

If you choose ::/64 as your loopback prefix, then you're specifiying a
range that includes all IPv4-compatible addresses (::192.0.2.1) and all
IPv4-mapped addresses (::ffff:192.0.2.1) in addition to ::/128
(unspecified) and ::1/128 (loopback).
