I'm surprised based on my experience: in 15 years of residential IPv6 usage I've always had the same IPv6 prefix (for a given ISP contract of course), even for those ISPs that insisted on handing out dynamic IPv4 with no option for a static one plus had no qualms renewing the IP at any moment, not just power down.

I'm seeing this the other way around: dynamic needs lease tracking while static just needs a permanent record attached to the already present auth mechanism.
