I share your opinion that "C-x 3 needs to work reliably for users
without resorting to writing elisp".

There you say:

   Someone seems to have made a very poor design
   decision in changing the way window-min-size works.

Now with emacs -Q evaluate the following forms

(defun split-window-right-ignore (&optional size)
  (interactive)
  (split-window-right (or size (/ (window-total-width) 2))))

(define-key ctl-x-map "3" 'split-window-right-ignore)

(set-window-margins nil 20 20)

do C-x 3 and look at the resulting windows.  That's what I would call a
"poor design decision".
