If IPv6 is going to pass through the present litany of compliance bodies
then Firewalls and NAT are here to stay.  PCI requires both, HIPAA doesn't
specifically, but there's no other way to meet the privacy requirements
without them and now Microsoft's new PII standard has similar wording to

The requirements for security were developed because of known issues as
mentioned and, since none of the RFC's seem to say "IPv6 will make up for
bad coding, bad applications, networks and systems installed and maintained
by "bob the computer guy" then IPv6 better be able to do everything IPv4
does when it comes to established security criteria.

The real world can be a drag.
