I've been following this tech for a while and I assure you it's being worked on and looked at seriously. I absolutely think it will exist in the future. Likely for very low bandwidth text messaging or maybe very low quality calls. Obviously, it will only work outside with line of site. I don't think it's ready for the next iPhone though. I would be very shocked and surprised if this capability was on the iPhone 13, not surprised if on the 14.
