I dont see that the big deal is about the no stop gas switches. Its for the apprentice tech class. Your not a tech diver yet, so its a tool that you can use to get use to doing gas switches, without betting your life on it. Just a training tool.
I agree. It is a good idea to teach the process before using live gases, at least at their TOD. What I'm questioning is how it's being sold.
