Sure, but when you take a NAT and replace it with no-NAT there will be no-NAT regressions as a result. Perhaps doing 66 w/ ULA would provide a comparable experience? IPv4 and IPv6 are enough alike that 99% of things “just work” but it’s in the 1% of ARP v NDP, is what we’re talking about here. - Jared
