If there was a small gap between the top of the physical keyboard and the touch bar, that might be enough to prevent false taps. Or I have to hack the Touch Bar to figure out where I'm accidentally hitting it, and don't put any buttons there.
I'm also triggering false taps on the Touch Pad, which never used to happen. I suspect if there was another gap between the bottom of the physical keyboard and the top of the Touch Pad, this wouldn't happen.
