Given the prevalence of one click install NASes (and by that I mean that Plex is a one click install, or even the whole *arr stack), I wouldn’t be sure.
Also that doesn’t account for people who are limited by available ISPs - some of us only have the choice of a single ISP, who might not be offering static IP, and CG-NAT makes port forwarding impossible. IPv6 would fix that but given we’re not much better off than we were ten years ago… I don’t have high hopes.
