Alterative door sensors with a Smart Lock?

As I understand it, the Nuki Door Sensor is a surface mounted Bluetooth device that communicates the door status (open, closed) TO a Smart Lock.

Is this the only door sensor that is compatible with a Smart Lock?

I asked in the Mattter API forum about “Using/binding a Matter contact sensor?”
about the possibility of using a Matter device from the Sense by MACO range for
concealed installation. It was suggested that it would not be possible.

Is there any mechanism, current or planned, to communicate the door status from
a non-Nuki sensor TO a Smart Lock?

The sensor need not be a Matter device. It could use other technologies (eg. Zigbee) or even an intelligent camera monitoring the door to determine the door status.

Just to be clear, I am not asking to obtain the door status FROM a Smart Lock.
