SInce Samyang already has an RF lens out with AF, and no one to my knowledge has reported that high speed display or any other EF only incompatibilities have shown up, I'd say the mount issue is highly exaggerated.

Also, Canon isn't going to kill off third party access to its mount via lawsuit,etc. they do realize that it's important for the mount. They may not entirely like it, but they also know it's a necessary evil.

I agree with you. As a matter of fact, Canon is probably the manufacturer who gives third party players the best access to their protocol, and ensure the best backwards compatibility with older optics.

Canon does not give access of their protocols to any 3rd party makers, a Canon rep has said so - I've read the interview some years ago. 3rd party makers have to reverse engineer the mount.

they may play lip service with the RF mount because of the desire to get it established.

A rep wouldn't necessarily know what Canon Japan is doing via side channels with sigma, tamron,etc.  Unliike the EF mount, it's in Canon's best interest to get the mount established quickly.
