As a long time emacs user, I've always had cap-locks mapped as my control key (plus the emacs key-bindings work in html forms and in anything using gnu deadline) which is a bonus. So on my MBP with touch-bar, I have had this mapping so I can have a physical ESC key:

CAPSLOCK -> CTRL LEFT CTRL -> ESC

It's not great, but it works. The last time I had to deal with a company who put the ESC key in a weird place was back in college where we have several of these HP Apollo/720 keyboards:
