There are quite a few third party RF mount lenses available if you don't need EXIF data or AF, so there doesn't seem to be an actual enforceable ban.

In Europe there has been a right to make aftermarket accessories for many years, decades in fact. But there is no obligation on the part of the manufacturer to provide any information to help. More importantly this right doesn't overrule any patents which might be protecting whatever goes on inside the RF lenses. So you not only have to reverse engineer, you also have to come up with a solution which doesn't infringe Canon's IP.

A solution which doesn't infringe IP is pretty much the definition of reverse engineering. .

Well, yes, it is :-). I only meant to comment on one thing you said, which was that "there doesn't seem to be an actual enforceable ban" on lenses which don't communicate with the body. That's correct, and it's a matter of law in Europe at least - I don't know about elsewhere.

I have a Laowa 85/5.6 2:1 macro with an RF mount, and Canon will never be able to take any action against it.
