Especially, when compared to renumbering IPv4 with DHCP, DNS is the biggest hassle in both cases.  This might have been different if we were able to figure out A6 records, or something like them.

If you think DNS is the biggest hassle in renumbering, you have never renumbered a complex environment.

The biggest hassle in renumbering any complex real-world environment is the number of
places your addresses appear in configuration files you do not manage.
