Is this what you have in mind?

(defun delete-other-windows-soft (&optional arg)
  (interactive "P")
  (if arg
      (delete-other-windows)
    (let* ((w (window-child (window-parent))) (wl (list w)))
      (while (setq w (window-next-sibling w)) (push w wl))
      (dolist (w wl)
        (when (and (not (eq w (selected-window)))
                   (not (window-parameter w 'no-delete-other-windows)))
          (ignore-errors (delete-window w)))))))
