Ring Integration: Reinstate camera motion sensors

The problem

I have 11 Ring cameras of various models and ages linked to Alarmo. This was working normally with some older cameras, but recently, after adding some new cameras, the motion sensor entities failed to load correctly for all cameras.

All old and new cameras are apparently successfully integrated using the HA Ring Integration. Most of the entities are present, but the crucial motion sensor required to trigger Alarmo (binary_sensor.xxx_motion) is now missing.
On the devices page it cannot be seen at all:

From the latest version of the documentation it appears that a policy decision has been made to withdraw the binary sensors and only provide the event! Why?

I implore you to reinstate all the binary sensors in the HA Ring Integration!

This cannot be difficult and will make the Ring devices such as motion sensors and doorbells compatible with other HA devices and alarm systems such as Alarmo.

Without these sensors, complex technical steps are needed to interpret the Events for each camera:

  1. Create a toggle helper
  2. Write an automation to respond to the motion event, turn the toggle helper n for 1 second then off for 1 second.
  3. Write a template binary sensor to convert the toggle helper to a binary sensor
  4. Add this binary sensor to Alarmo etc.

This works, but why make it so complicated?
