It's sad to see all that work going to bin.

Did you know that you can get touchbar on ipad that you connect as a second monitor? Excellent way to keep it alive, except, oh, it does not work, unless you drag the window to the ipad first... I mean... Somebody went and designed it to work like that, on purpose...

From the security perspective, having some UI that cannot be controlled by apps (a led, a touchbar, whatever) is very important for signalling app privilege levels. oh well
