I don't think the touchbar was going to be worthwhile without haptic feedback. At the very least, it needed the force sensors used for the touchpad so that accidental touches could be properly rejected.

The amount of times I mute the audio with that stupid touch bar..

There are a few unicode characters I keep finding myself needing to type when I transcribe, and the Touchbar would be perfect for this. Except, there's no good way to just "add keys for that". You have add quick actions, which means writing Applescript that copies those into the clipboard and pastes... this is slow enough that it's noticeable (never mind having to first hit the quick actions button). On top of that, even though the label for the quick action is that single character, the buttons that it renders are like 2 inches wide. So instead of being able to fit 20 such buttons/keys on it, I can fit exactly 6. You have to swipe left and right to see the others.

Is there a Minecraft extension so that the Touchbar becomes the game's hotbar with icons? I've never looked.

I've said this before but the trackpad is too big and they could have fit both function keys and touch bar and everyone would have been happy.
