> (Technically I guess you could do without NAT if you gave every host on your LAN two addresses: a private address and a publicly-routable one. But that might be more cumbersome.) Except that the IPv6 standard explicitly allows for two on-link prefixes for SLAAC. So in my home I have a ULA address range that is static, and all my devices get a SLAAC random IP from my ISP. If my prefix changes, that doesn't change my ULA prefix and all DNS records will continue to function. My ULA is also advertised over BGP using Wireguard, so its automatically routable from VPN when I am on the road but I still want to reach internal resources.
