I guess an advice might work (it probably wouldn't need to put the map
back, just let-bind a variable that causes the filter function to return
evil-normal-esc-map without bothering to sit-for).
But it doesn't sound very appealing.

Maybe "enable evil-esc-mode in post-command-hook and disable it in
pre-command-hook" might work?
