 From my understanding and contact with Comcast they will support DHCP6 
clients, e.g. windows and mac when connected without a router. I do 
believe they have disabled SLAAC.

The few pfSense installs I had access to had a DHCP6 address on the WAN 
too. Perhaps yours only requests a prefix, which is valid. I'd just 
expected it to request both a prefix and a address.
