I still don't understand why they shifted from 0:: to ffff::
but point stands, ipv6 is exactly ipv4+, except yes, they did redo arp. I don't think its really that much better...but really? that's what turns something from great into awful?

I think the most reasonable explanation is probably because they thought ::1 being loopback (otherwise it would have to go above 255.255.255.255) was more important (since it would exist as long as IPv6 does) than the transition encoding that presumably would die off over time.
