In what sense is this new?

I also get the feeling this is a hack for the sake of a hack.  Is it
really that much better than the "classical"

--8<---------------cut here---------------start------------->8---
(let ((up #'previous-line) (down #'forward-line))
  (when button
    (setq up #'backward-button down #'forward-button))
  ;; ...
  )
