> With NAT you were just guaranteed that this would always be safe. Another safety benefit of NAT is that if you use a private IP address block (ex 192.168/16) you can be reasonably certain that your devices aren't publicly routable without bothering to actually check the router firewall configuration. This is particularly nice for home networks - I don't usually want my home devices to be reachable from the internet at large. To understand what I'm getting at here, imagine trying to walk an elderly relative through verifying their firewall configuration over the phone. A simple command to check the IP address was enough with NAT.
