Xfinity "TV Provider" for Xumo streaming box?

When will Comcast (Xfinity) become a formal "TV Provider" on the Xumo platform?  During initial setup, one can select from Xumo and Spectrum (Charter's brand) as TV providers, but Xfinity is not an option.  While one can use the Xfinity Stream app, such an app is different than being able to chose the primary TV provider to be Xfinity.  Thanks for your consideration.
