AFAICT pretty much all home ISPs don't offer persistent delegations. Mine changes with every power outage plus a few other times a year. You can upgrade to their "business plan" and pay 4x as much for 1/2 the bandwidth to get a persistent delegation of a /48, but "Having more than one device on the internet" shouldn't require a business plan these days, and so the choice is NAT66 or having all the issues that that RIPE publication calls out.
