I've now clarified that section...

unload-feature does in the Coding Conventions section in the manual.

Hm...  does unload-feature remove advices?  Let's see..

Well, there's this:

(defun loadhist--unload-function (x)
  (let ((fun (cdr x)))
    (when (fboundp fun)
      (when (fboundp 'ad-unadvise)
        (ad-unadvise fun))

Hm...  but is that what it does?
