I believe that standard comes from the adaptation of conventional doorbells installations. In my opinion, what I see trending, is people wiring their houses for NVR systems with Cat5/6. In this scenario, a simplistic and cheap doorbell hardware, that connects to a PoE NVR and delegates all the object detection there, sounds far more valuable than a supercharged doorbell.

As you said, they exists but are rare (and expensive). It seems to me there is a niche market that nobody is recognizing and taking advantage of.

Personally I put in a standard doorbell wire, and then a Cat 5 wire above the door for a camera.
