So, if the new DS always disables the robot without a (preferably normally closed) switch connected to the competition port, then all is well with the functioning of the new system. It can obviously still be jumpered around with a soldering iron, etc., but it generally makes it much more difficult to kill yourself.
That is exactly the behavior of the competition port on the Driver Station. You've also done an excellent job explaining the rationale behind the reason to change to a "normally closed" switch (for enable) from the prior behavior with the IFI operator interface. Thanks!

This does mean, however, that a team always has to have their switch on hand in order to enable the robot.
