Not true. The Netgear CCB tried to install here just a couple of days
ago is IPv6 capable. Unfortunately, it breaks IPv4 by not being
capable of bridge mode and insisting on NATing everything inside
unless you subscribe to static IPv4 addresses from Comcast.

What's the model number? The Comcast techs here are quite insistent that none of the CPE capable of routed subnets are able to do IPv6.

OTOH, you can supply your own Motorola Surfboard DOCSIS 3 modem and
it works just fine with Comcast Business.

Have you tried using that with a routed subnet?
