 In the `WP_REST_Server`, a `preg_match`
 [https://core.trac.wordpress.org/browser/trunk/src/wp-includes/rest-api
 /class-wp-rest-server.php?rev=35353#L774 call] and an if-check can be
 moved one level of for-loops up.

 It doesn't depend on the `$handler` variable nor is it modified in the
 inner for-loop, so that this would save some `preg_match`/REGEXP
 iterations.
