That's a bit of a pain if you put that into muscle memory and use other Vi interface software that can't be remapped. Personally I'm in the Caps to Ctrl and use Ctrl-[ for escape camp. Works in my shell, REPLs and in my database clients and anywhere else with a readline interface that isn't Vim. Even with that I still want a physical escape key.
