This is entirely legitimate. IPv6 is actively confusing in what "enabling" means - is there a firewall, and under what conditions are ports opened? Is there mandatory use of privacy addresses from clients, and is there any protection from clients who generate SLAAC addresses from their MAC address? Is there a NAT? (NAT66 is a thing, but very few people implement it.) The mental model of IPv4 NAT is much more straightforward and I would strongly recommend that home users prefer that.
