Or `point' (not `point-min'), that's another thing to think
about ... but that maybe depends on the particular function,
or more so at least, what to do from Lisp with no supplied
boundaries _but_ a region, if you have a good answer to that
I think it would hold for all such functions ...
Here, compare ... ?

(defun test-dwim (&optional beg end)
(interactive (when (use-region-p)
(list (region-beginning) (region-end)) ))
(or beg (setq beg (point-min))) ; or (point)
(or end (setq end (point-max)))
;; insert code here
;; now let's just make a list to do something
(list beg end) )
(defun test-dwim-2 (&optional beg end)
(interactive (when (use-region-p)
(list (region-beginning) (region-end)) ))
(or beg (setq beg (if (use-region-p) (region-beginning) (point-min))))
(or end (setq end (if (use-region-p) (region-end) (point-max))))
(list beg end) )
