I don't recall any discussion about the need for that change, but
I guess there was a reason....

But I second your idea of using window=t to get the canonical list.


In any case, you can still get a canonical window list from lisp;
edebug does it like this --- you can probably tweak it to
your needs:

(defun edebug-window-list ()
  "Return a list of windows, in order of `next-window'."
  ;; This doesn't work for epoch.
  (let (window-list)
    (walk-windows (lambda (w) (push w window-list)))
    (nreverse window-list)))
