I also have press-and-release option/alt for esc, but sometimes get lazy and try to hit the tiny touchbar icon for esc.
A physical escape key will be nice to have, and inverted T arrows will be really nice to have.
I wish they'd added haptic feedback to the rest of the touchbar, but I'll take it.
This might be in part because I'm a tall man, with large hands and long fingers, and also Esc normally has more of a separation from adjacent keys than capslock does.
But another reason I don't want to remap caps lock is that when I am typing on a coworker's computer, odds are high they don't have things remapped the same way. Imagine looking like an idiot in front of your peers, because your muscle memory makes you not know how to type :)
(Also, I'm not sure if people who do that remapping swap caps lock with a different key? Personally, I fully utilize the caps lock key - it wouldn't be much of an improvement to put it in an unusual location, and getting rid of it is not something I'd consider.)
tl;dr - Different people have diverse habits, preferences and needs. Apple's challenge is to design a keyboard layout that works well for as many as possible.
