Let's say when your ipv6 prefix changes it is almost the same situation. Only that ipv4 bundles all traffic of all devices on one ip which obfuscates a bit.

But having the ipv6 prefix change you get a pile of problems (DNS, firewall), you don't have with ipv4.

The IPv6 prefix changes are disruptive, I agree. My prefix has been stable for a couple years, but on another ISP it would change every few months and was certainly annoying.
