That's fair. Personally, I used the tactile function keys for exactly six things (brightness up/down, volume up/down, mute, play/pause). Those six functions are now available on my touchbar. They're no longer tactile, which, yes, is a minor inconvenience. I wouldn't use a touchscreen for touch-typing code, of course. But for a handful of buttons way off the home row, it doesn't affect me much.

In exchange, I get to add other buttons which can also display customizable state. Yes, zoom has a global shortcut to toggle the mic. The problem is, the mic state is not visible on your screen unless the zoom window is visible. This is a frustrating design flaw IMO, which really should be addressed in some consistent way across every phone/video app. But, it's not, and so I need to pay attention to my mic state. My touchbar button toggles the mic, and displays the current mic status. I would imagine that every phone/video chat app is similar.
