I actually took this to heart and deployed it natively on multiple VLANs in my home. Then, even with the abundance of address space, Comcast pulled the ability to use IPv6 in this manner and I'm back to to using NAT on all my VLANs except for one. Progress.

Can you expand on this?
It's been a while since I've explored IPv6, but I'm on Comcast and I recently switched from OpenWRT to an Ubiquiti router and was surprised that 1) it doesn't enable IPv6 by default and 2) It asks for configuration [2] that I'm not sure how to answer. I thought everything "just worked" with Router Advertisement.
In a nutshell, Comcast used to provide a /60 to residential customers and this could be subnetted into more than one LAN. Nowadays they only provide a single /64 and this can only be used for one subnet.
It sounds like your router can request a larger prefix length than /64 and Comcast will give up to a /60. That requires a router that knows how to do that.
That seems like reasonable approach when most people just need /64, and those who want more have to configure to get it.
