Netgear CM3000 still supported for NextGen speeds?

I checked the list of compatible modems for next gen speeds today and I remember seeing the CM3000 on the list. It's not on the main page but lower on the page, if you click on the "See all modems" then on "Compatible modems for enhanced speeds", it's listed there but without the upload speeds. Does Xfinity still provision that modem? Thinking of getting it if the Arris S34 isn't coming back in stock anytime soon.
