That'd be the dangerous bit.  I've got a defconst called -functions in
some of my code, but it wouldn't be hurt.

Those with a custom-type of 'hook or '(repeat function) could be likely.
In fact any var with that custom-type might be ok to act on.  A grep
finds me three called -functions (code below)

    find-directory-functions
    auto-coding-functions
    compile-command-default-functions

of which auto-coding-functions may be the only important one not
presently in unload-feature-special-hooks.




(pp (let (ret)
      (mapatoms (lambda (sym)
                  (and (boundp sym)
                       (get sym 'custom-type)
                       (not (memq sym unload-feature-special-hooks))
                       (string-match "-functions\\'" (symbol-name sym))
                       (push (list sym (get sym 'custom-type)) ret))))
      ret)
    (current-buffer))
