After uncommenting, how do you know which lines should be recommented?
Do you remember them in some variable? Or do you wrap the code parts in
those (ugly) +begin...+end "brackets"?
Do you uncomment all comments, or only those that "look like Org stuff"?

Why do it line-wise?

It looks like the exact meaning of such a function is slightly different
for every one, so such a function would need lots of hooks and config
vars to cover all cases.
But you can write your own function starting with
(defun my-uncomment-region (beg end)
(let (spt)
(while (and (< (point) end)
(setq spt (comment-search-forward end t)))
(let ((ept (progn
(goto-char spt)
(unless (or (comment-forward)
;; Allow non-terminated comments.
(eobp))
(error "Can't find the comment end"))
(point))))
(uncomment-region spt ept)))))
