I agree is more intuitive, and it works in `replace-match', or instance:
(mapcar
  (lambda (group)
    (let ((str "foo123"))
      (when (string-match "[a-z]+\\([1-9]+\\)" str)
        (replace-match "bar" nil nil str group))))
  (list 0 1))
=> ("bar" "foobar")

Are you willing to write a patch to implement it?
