I think the problem with ipv6 is that people may enable firewall rules on ipv4, but completely forget about v6. With auto configuration you may be leaving yourself wide open.
By all means enable ipv4 and v6 but remember to ensure you firewall both.

My IoT network has a very controlled list of allowed outbound targets in the ipv4 world. If I blindly enabled IPv6 I’d have to ensure I protected against that too.
Of course I also do things like intercept UDP/53 and nat it to my pihole as some devices have hardcoded dns servers, which many purists claim is an “ugly hack”.
