(Yeah, the escape key was taken out as well at first, but then it was brought back, and people still were quite hateful toward the touch bar after that.)
- It couldn’t be used without being looked at, due to it having no physical keys
- It was always kind of hacky, being essentially a long thin Apple Watch (down to running a watchOS variant) that would occasionally freeze up
I think it would’ve been better received had it been composed of Stream Deck-like display keys powered by macOS itself which would’ve brought much of the dynamicism of the touch bar while also keeping tactile feedback and eschewing bolted-on watchOS-variant bugginess.
Mind you, a majority of the useful "things the touchbar can change into" involved non key-shaped interaction surfaces. The volume and brightness sliders; the iMovie/FCP video scrubber; the keyboard autocomplete suggestions; etc.
The only way this would have worked is if arbitrary regions could have been dynamically raised/tactile-ized to match the interaction elements being shown.
That said, a touchscreen with software-positioned raised areas would be very neat, if it existed.
From 10,000 feet up, all we really need are some mechanical actuators to allow it to be segmented in a way that can be felt.
(Or. Electromagnets, and ferrofluid. Under the display.)
My Caps Lock key is a Control/Escape key (when tapped it behave like a Escape, when hold it's Control), and my left Control is a one shot layer switch key [1], which means I tap LCtrl once, and then press Caps Lock + 5 to get Ctrl+F5. Doable with single hand and more ergonomic as I have an unusually small hand.

2. If I did, I would've either remap it or create a layer to make pressing it easy.
Your full size keyboard is an ergonomic prison.
