I think what is now proprietary is the 6 bit coding for Leica lenses. Identification of the lens in use is important in digital because of the corner color shift corrections etc that need to be made. So, someone like Fuji may have to make a menu so you can tell the camera what lens you just mounted.
If you look at Zeiss and Voigtlander M glass, none of those lenses come with factory 6 bit codes. they are all done after the fact with lens mount swaps or through the menus.
