New Remote: Circular Scrubbing?

Is the new scrubbing feature of the updated Siri Remote only compatible with the built in video player or can it be implemented for channels?

For anyone unfamiliar, the outer ring of the d-pad on the new remote can function similar to the old ipod navigation. If you pause the video and leave your thumb on the outer ring for just a moment, you can then scrub through the timeline in a continuous circular motion. When it is active the timeline will show a specific icon to let you know, as seen below...
