Since most applications do not use the match data in practice, I think
if an application use the match data, it should require it explicitly.
I.e., please take a look at the following:
;; Normal applications (no use of match data).
(if (string-match "foo" bar)
;; True branch.
;; False branch.)
(foo-bar)
;; Applications that use match-data.
(if (string-match "foo" bar)
(with-match-data (match-data)
;; True branch.)
;; No need to use `with-match-data' here, since there is no
;; match data.
;; False branch.)
(foo-bar)
And of course functions like `string-match' do not set match data by default, as if `inhibit-match-data' is turned on by default.
