SLAAC and DHCPv6 actually make a ton of sense, along with the other features of IPv6. I think you need a lot of experience in both networking and applications, at many scales, to understand the design decisions and appreciate how useful they are in which contexts. That said, you could publish a clear playbook for an ISP of residential Internet for ipv6 adoption, it wouldn't change much, because they are not deciding to adopt ipv6 based on either its aesthetics or its technical merits.
