> I agree that the option should be available to those who still have autologin enabled.

+1. It should be disabled when the password is locked, not when autologin is enabled. Autologin and password locking are different concepts, and I don't see a reason to disable screen locking when having autologin. After autologin you are in a fresh session, but with a locked session you might currently work on sensitive documents, or typing a private mail, or what not.
