True. I showed you an example what the ring has been used for many years, in fact on Canon lenses as well. Granted, perhaps not in the recent years.

Canon EF lenses never had aperture control rings. Their electronic apertures are controlled by camera controls.

Canon has added electronic aperture controls to RF lenses and to one of their EF to RF adapters.
