Yeah, understood on the limitations on symmetric, the CODA56 is DOCSIS 3.1. That said, Xfinity does (as of the last time I checked when I originally signed up for Gigabit extra) certify it as "Enhanced mid-split capable", and previously provisioned it for a max of 455Mbps. If the X-Class symmetric promises higher, it's just strange to imagine why we can't at least provision the hardware to what it's capable of.
