This all thread is focussing at today's network.
Does it make any sense in _today's_networks_
to turn off private v4 and translate v6-only instead?
Maybe not.
Simple reason: what works and what does not work
is 99% the same, so no need to change for something
that is still unproven technology.

However, the real question is for network in the future.
Please, let's think for a minute at 5 or 10 years for now,
when IPv6 will be mainstream technology, but a lot
of the Internet is still IPv4 only.

Say that someone want to build a large network from scratch,
whre hosts usually communicates with each other but
need from time to time to communicate with IPv4 'things'.
Do you want to tell this person that he/she needs to also deploy
IPv4?
