As a macOS user, I'm pretty pleased Apple is discouraging the use of the Touch Bar as yet more real estate for 'innovative' developers to plaster unwanted notifications or other distracting garbage. Besides, if you have a compelling non-approved use of the touch bar nothing is stopping you from distributing it outside of the Mac App Store.
Now if only they could take a look at the user-hostile default "allow" option on the dialog Safari presents when a website wants to start sending you push notifications...
