I have not looked at the specific proposal. I am very happy to go away and have a look at exactly how that would work. The one thing that that would have in its favour is the point I made about time to adapt. Within reason, if you have time to adapt, you can say “Okay, how do I configure around a particular system?”, if that has a combination of certainty to it and a length of time to adapt. As principles, those are helpful things to have.
