We use it in info.el for the symbols.

"No effect" in the sense that if the default face uses a proportional
font, fixed-pitch defined as above still uses a proportional font?

I actually meant something like this:

  (defface fixed-pitch
    `((t :font ,(font-spec :spacing 'M)))
    "The basic fixed-pitch face."
    :group 'basic-faces)
