I may well be misunderstanding what you mean here, but if you

;;;###autoload
(defun foo ()
  (declare (obsolete nil "25.1"))

then that obsoletion form also makes it into the loaddefs file, so this
seems like it should already work?

Or is this something that's been fixed in the decade since the bug
report was opened?
