 Apparently `post_author` is a string in the WP internals,
 "[https://core.trac.wordpress.org/browser/tags/4.7.2/src/wp-includes
 /class-wp-post.php?marks=34#L31 for compatibility reasons]".

 In `WP_REST_Posts_Controller` we
 [https://core.trac.wordpress.org/browser/tags/4.7.2/src/wp-includes/rest-
 api/endpoints/class-wp-rest-posts-controller.php#L1469 cast it to an
 integer] before returning it in the response.

 In `WP_REST_Revisions_Controller` we
 [https://core.trac.wordpress.org/browser/tags/4.7.2/src/wp-includes/rest-
 api/endpoints/class-wp-rest-revisions-controller.php#L346 don't do the
 corresponding cast].

 The result is that the `author` ID is returned as a string, even though it
 is documented as an integer for both
 [https://core.trac.wordpress.org/browser/tags/4.7.2/src/wp-includes/rest-
 api/endpoints/class-wp-rest-posts-controller.php?marks=1896#L1893 posts]
 and [https://core.trac.wordpress.org/browser/tags/4.7.2/src/wp-includes
 /rest-api/endpoints/class-wp-rest-revisions-controller.php?marks=472#L469
 revisions].
