[ Note: I use `outline-minor-mode` systematically in all my Elisp files.  ]

I don't have a strong opinion on this, but FWIW, I have a slight
preference for the ";;;;" version over the ";;;" version (but it's very
slight; I'm really OK either way.  In most cases I don't even notice
the difference).

The annoyance you mention doesn't affect me, because I use

    (hide-sublevels (if (eq outline-level 'lisp-outline-level) 1000 1))

to fold most of the actual code when opening the file but none of the
headings.  More specifically, I get something that might look like:

    ;;; foo.el --- Blabla
    ;;; Commentary:
    ;;; Code:
    (require 'cl-lib)
    ;;;; Custom vars:
    (defcustom foo-var nil...
    ;;;; Aux functions
    (defun foo-fun1 (arg)...
    (defun foo-fun2 (arg)...
    ;;; foo.el ends here

[ And I (almost) never toggle the folding or fiddle with it by hand,
  I only use `reveal-mode` to auto-unfold/refold as I move about the buffer.  ]
