Lately the `register'-part of
`copy-rectangle-to-register' turned out not as suitable
for my needs. Tried to get rid of that.

What about such a thing?

(defun copy-rectangle (start end)
  " "
  (interactive "r")
  (let (extr)
    (dolist (elem (extract-rectangle start end))
      (setq extr (concat extr elem "\n")))
    (kill-new extr)))
