I've to admit that I have a soft spot for Zenitars ;-)
What is public status of every mount?
As far as I know
L mount - open standard
4/3 - open stadart
FE - open standart
RF - ??? no idea
Z - ?? no idea

Lets say I'm Sigma, Tamron , Tokina, Chinese startup or Russian optics manufacturer. Do I have access to current RF/ or Z specs? Am I equal member in such aliance? Can I influence future development of the standard?
