For me? Because I can't tell without looking at the keyboard whether it exists or not (and potentially whether it's been moved by some program's integration with the touchbar).
I've been touch typing for years now, and the idea that I have to look down at the keyboard to see if a key exists (a key that that has existed for the entirety of my computing history) is ludicrous.
