There's an awful lot of inertia in the "NAPT/firewall keeps our hosts 
safe from the internet" mentality.  Sure, a stateful firewall can be 
configured allow all outbound traffic and only connected/related inbound. 
When someone breaks or shuts off that filter, traffic through the NAPT 
firewall stops working.  On the stateful firewall with public IPs on both 
sides, everything works...including the traffic you didn't want.

People are going to want NAT66...and not providing it may slow down IPv6 
adoption.
