> And the tools for managing IPv6 firewall rules suck on "SMB grade" stuff like ubiquiti and are virtually non-existant on any consumer grade router. If I have to SSH into the router and treat it like a "real" router to set up IPv6 firewall rules... it is never gonna fly for anybody who isn't proficient with "real" routers (i.e. >99% of the world).

Umm, the IPv6 firewall interface is exactly the same as the IPv4 firewall interface on UniFi[1].
