There are quite a few providers in the world that run Dual-Stack Lite (native IPv6, IPv4 is tunneled to provider-run NAT gateways) and they all hand out consumer-grade gear.

Since the OnHub only comes with Ethernet you'd have to put something between it and the wire anyways of course, but it then has to be more than a dumb modem, and you'd be forcing all traffic through the tunnel.

IPv6 isn't without problems, but many people use it without noticing, through consumer devices way cheaper than this. The ones complaining the most are the enthusiasts which suddenly can't reach their home server via IPv4 anymore.
