Nobody will stop you to go to  RIR and argue for a PI address space for 
IPv6. You will be able use PI IPv6 address similarly as you used PI IPv4.

In IPv6 you have additional options next to static and DHCP the 
autoconfiguration. Since autoconfiguration was developed earlier this 
assumed to be avilable most of the IPv6 implementation. You can argue, 
that DHCPv6 client support is vital part of IPv6 node requirements...
