I thought they might be important. I'm not really sure what the
user-visible effect of those are though. But perhaps if you're not
interested in them, we should just add a function that does only what
you want?
(defun rectangle-columns (start end)
"Return cons (START-COLUMN . END-COLUMN) of rectangle columns.
START and END are buffer positions of the rectangle corners."
(save-excursion
(let ((startcol (progn (goto-char start) (current-column)))
(endcol (progn (goto-char end) (current-column))))
;; ensure the start column is the left one.
(when (< endcol startcol)
(let ((col startcol))
(setq startcol endcol endcol col)))
(cons starcol endcol))))
