IPv6 is a total mess; it was intended to be a clean break from IPv4 and do things more correctly. Turns out that they didn't really think it though; besides more bits anything from IPv6 was either easy to add to v4 or turned out to be a bad idea (like SLAAC). It should never have been adopted in the first place but now it's the only practical option for moving forward.
