OK, I'll revert the deletion.
And speaking of .elc compatibility... I have a little major mode
derived from emacs-lisp-mode via `define-derived-mode'. When I compile
it with 21.4 I can use it on 21.4 and 22.0.X; however, when I compile
it with 22.0.X it fails on 21.4 (it does not produce an error, but it
doesn't work either). I think the problem may be related to the use of
`delay-mode-hooks' on newer derived.el, but I'm not entirely sure.
However, the question is: should I expect for a 22.0.X .elc file to
work on 21.4? I would've assumed "not", but for this comment on
`define-derived-mode':
;; Run the hooks, if any.
;; Make the generated code work in older Emacs versions
