But the point of my post is that FD lenses wouldn't be usable on EOS bodies even if the registration Was kept the same so why bother To keep the regisration the same? EOS bodies don't have the FD apeture actuator Do they?

They allow it with an actuator pin. Think of it as the reverse of a K lens. We mount the lens and it opens up, they mount the lens and it can then stop down if the actuator arm is deflected. Even if the FD mount wasn't suitable for adapting, they still broke your cardinal rule about the importance of long term support for their lenses.
