I came across this tip of an iceberg in the commentary.

#+name: xxx-byte-opt-el
#+begin_src emacs-lisp
  ;; "No matter how hard you try, you can't make a racehorse out of a pig.
  ;; You can, however, make a faster pig."
  ;;
  ;; Or, to put it another way, the Emacs byte compiler is a VW Bug.  This code

  ;; to get it there.
#+end_src

If a big advance from an Industry player, such as FB, were to release a
JIT, that the GNU Emacs legal dept. does not object to, does that help?
