As an old Sun keyboard user, Caps Lock as Control feels right. That's also where it is on my HHKB keyboard.

As a vim user, escape is too high up on most modern keyboards anyway. The ADM-3A terminal vi was invented on placed it to the left of the Q key, which was a lot easier to reach. HHKB puts it where the tilde key traditionally is, which is pretty close to the original intent of vi.

Remapping tilde on touchbar MacBook Pros would be a good solution, if there was an obvious other place to put tilde/backtick.
