FaceTime camera for Apple-TV

It seems to me that Apple could do this by releasing either a bluetooth or wired camera that can be positioned on the top center of your TV. If wired the thin wire would just come down and plug into the USB-c port that right now says it is for service. Even allowing a bluetooth connection with an i-phone camera. Then a phone holder could be fashioned to hold a phone at the top center of the TV allowing people and families to do couch to couch FaceTime calls.
