Proper way to setting hydra-key-doc-function without affect other package's setting

[wztdream]

I am using spacemacs, and by default spacemacs set hydra-key-doc-function to their own format

(defun spacemacs//hydra-key-doc-function (key key-width doc doc-width)
  "Custom hint documentation format for keys."
  (format (format "[%%%ds] %%%ds" key-width (- -1 doc-width))
          key doc))

But this will results annoying brackets if you use :column property in hyra, for example the code in hyra example will be:

(defhydra hydra-movement ()
  ("j" next-line "down" :column "Vertical")
  ("k" previous-line "up")
  ("l" forward-char "forward" :column "Horizontal")
  ("h" backward-char "back"))

We can solve this issue by setting hydra-key-doc-function to default value, but I think there is some "reason" for spacemacs to setting their own format. So here is the question is there any way to setting my own hyra format without break other package's setting, like the setting by spacemacs here?
