Fair enough, I didn't go through the math. I don't think many NATs are realistically likely to let a single client run 64k sessions.

ISPs are increasingly putting customers behind CGNAT, so wireguard at home doesn't imply control over NAT policies. Especially new entrants and fixed wireless ISPs don't tend to have the resources to get an IP (v4) for every customer, and some of them don't offer v6 either, so having some form of hope would be nice.
