I have just asked on #emacs whether I can customize the fonts,
colors of the frame of the *Help* buffer, and I was asked by 2
persons to report this problem here.
I don't think the absence of such a feature is a bug. I would not
object to adding such a feature, but now is not the time for that.
What is meant by the missing feature that would be added? I don't understand
what is being requested.
I just add an entry to `special-display-buffer-names' to customize the
*Help* buffer's frame (standalone, in my case):
("*Help*"
my-display-*Help*-frame ; display fn raises the frame
((background-color . "Thistle")
(mouse-color . "Blue Violet")
(cursor-color . "Blue Violet")
(height . 40)))
And there are other ways to customize a *Help* frame. What's missing?
