What kind of self-respecting Vim user physically reaches up to the top corner of their keyboard constantly?
Even if you have a physical esc key up there you should be hitting ctrl-[ or remaping it onto the capslock. It's wasted motion to constantly pull off home row to hit escape.
The Vim wiki has a lot of tips for more efficient mappings[1], but if you don't want to be dependent on your own idiosyncratic config, ctrl-[ is literally the keycode that the physical esc key generates, and it's soooo much easier to hit there's no reason not to retrain your muscle memory to prefer it.
I do remap the function bar right now, though. That will take some getting used to.
And remapping your vim shortcuts is great - when you're not constantly logging in to new instances or (don't ask) sharing logins with co-workers.
Besides, no one who uses Vim is gonna be happy to see the physical Esc key go away.
