How would that help in the help-default-arg-highlight case? You cannot
do

  (face-font '(:italic t))

or

  (face-differs-from-default-p '(:italic t))

Are you proposing that the italic font be used by default, i.e.

(defun help-default-arg-highlight (arg)
  "Default function to highlight arguments in *Help* buffers.
It returns ARG in lowercase italics, if the display supports it;
else ARG is returned in uppercase normal."
  (if (face-differs-from-default-p 'italic)
      (propertize (downcase arg) 'face 'italic)
    arg))
