It still looks like NAT to me.
Almost all the people, perhaps other than you, accept NAT
as is to keep IPv4 Internet or as part of transition
plan from IPv4 to IPv6.

NAT is a disgusting hack and destroys the universal peer to peer
nature of the internet in favor of a consumer/provider model.
As I repeatedly pointed out, end to end NAT is clean preserving
the universal peer to peer nature of the Internet.

The basic idea is to let NAT boxes perform address translations
only without adjusting check sums or translating ports and
to let end systems perform reverse address translations,
which restores correct check sums, and port number
restrictions.

I have yet to find an economical way to manage a business merger involving two large rfc1918 networks where end to end 
peering is required and which partially or fully overlap. Ignoring short-sighted financial management views, the best 
long term solution is globally unique IPv6 addressing wherever possible. Local islands of IPv4 gatewayed or NATted with 
local management continue to be possible.

In other words, once its merger time, IPv6 fixes nothing.

Can one really incentivize an enterprise to standardize on IPv6 on the basis of it will make a future merger much more economical? And this is well before any such prospect usually exists.

Is there any activity that enterprises choose to engage in on that basis?
