It is common knowledge since the introduction of RF....
The cameras switch to EF protocol when an adapted lens is mounted. The lack of extra pins on the EF lenses tells the camera what is going on. Not all RF contacts are being used at the moment, by the way. They are there for future additions of functionality.
There are many 3rd party EF to R adapters on the market, too.
