Long overdue for many different reasons, be they political (stop
the "nat doesn't exist in IPv6 nonsense") or practical, like the
ability to translate IP based services to new addresses.  For
instance it might be nice to translate an old DNS server IPv6 address
to a new working DNS server in some situations.

NAT has many more applications than it's most popular RFC1918 PNAT
to one IPv4 address, and IPv6 has been missing out on those other
tools due to the regious nature of the "private address vrs public
address" dogmas for that one, specific NAT application.
