Hmm... my reflex would have been to make use-package use something like

    (funcall (or (get variable 'custom-set) #'set-default) variable value)

instead of whichever other way it currently uses to set the variable.

Could you describe what would be the advantage of introducing a new
symbol property?

[ BTW: whichever way we end up going, I think that it would be better if
  use-package didn't use custom's symbol properties, so we should
  introduce a new function (I suggest to name it
  `customize-set-variable-external` to get the bikeshedding
  rolling ;-). ]
