Actually, Emacs doesn't _load_ simple.elc (put a breakpoint in Fload,
and you'll never see "simple" being loaded), it only locates it.  This
is because startup.el:command-line does this:

  ;; Convert preloaded file names to absolute.
  (let ((lisp-dir
           (locate-file "simple" load-path

(Armed with lisp-dir, it then proceeds to convert relative file names
in load-history into absolute file names.)

IOW, we use simple.elc as an indicator where the Lisp files reside on
the file system, which is the value of lisp-dir computed in the above

I don't see anything wrong with that.  Do you?
