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.
