A hook-based approach looks promising.

When such simplest prototype that demonstrates this solution
conceptually works well

  (progn
    (add-hook 'pre-command-hook (lambda () (other-window 1)))
    (add-hook 'post-command-hook (lambda () (other-window -1))))

then it could be extended by adding customization, etc.

If the code above doesn't work in all cases, this means we have a bug.
