Any form of communication with the current IPv4/IPv6 mixed internet, except for dual stack, also requires some sort of NAT.
Technically, A+P (address plus port) mapping is a bit different, but for the customer that doesn't make a lot of difference.
A+P is equivalent to end to end NAT, though end to end NAT only needs plain IP routers behind gateways, whereas A+P requires routers with A+P routing capability for large (but not very large) number of hosts. As networks behind the gateways are local and not so large, it can not be a practical problem.
And A+P has serious scalability problems.
No, not at all. Masataka Ohta
