The default is reaching to the top left corner of the keyboard. I know the default and it's terrible if someone uses vim. In macOS it's trivial to remap the caps lock key to ESC system wide through the built in preferences. So while it's not that way out the box, it's certainly in the realm of default configurations any user might make on their machine.

I can't really understand picking an editor that is so awkward that it relies on me reconfiguring my hardware and breaking the labelling of the keys to make it usable.

Here's the thing. Even if someone doesn't use vim, remapping a mostly useless key like caps lock to ESC is still more useful. ESC should cancel out of most dialogs and popups, so should be key that is likely used more often than the occasional times someone needs to type a long enough string of upper case characters to need caps lock.

As far as editors and key labels, I don't really understand the problem. Move beyond any of the basic shortcuts on any editor, and you quickly move into combinations that have little to do with what's written on the key(s).
