There is clearly a need to discover the NAT64 prefix:
draft-ietf-behave-nat64-learn-analysis
draft-ietf-behave-nat64-discovery-heuristic

Note that the analysis draft does not consider PCP. Maybe it should. 
Looking at the list of pros and cons for DHCPv6, PCP would be different, 
and better in some aspects.

Personally I would much prefer using PCP than the heuristic when PCP is 
available.
