Of course there are downsides to implementing NAT - adding any feature
to a device increases its complexity and affects its expense, time to
market, MTBF etc. And there is certainly a downside to *deploying* NAT:
NAT removes end-to-end transparency.

Gotta keep those SOHO users in their cages, don't want them becoming
independent producers of digital value, no sir!

Seriously - by all means keep NAT as a technology for those who want to
deploy it; we can't uninvent it anyway. It just shouldn't be imposed on
others.

I would argue that an ISP requiring of a customer that they use a NATted
solution with IPv6 *is* imposing it on others.
