IPv6 implementors are inconsistent in what they support. Eg Android and it not supporting DHCPv6 [1].
Also NAT in IPv6 is not as widely supported as it is in IPv4 (and yes NAT can and is used for reasons other than security, such as policy based routing and routers with multiple disparate WANs like Fibre and Cellular).
Plus there will always be someone somewhere with a middlebox, be it IPv4 or IPv6.
