Comment (by aaemnnosttv):

 @TimothyBlynJacobs is correct - it is currently possible to
 add/remove/change headers sent by a REST request using the
 [https://developer.wordpress.org/reference/hooks/rest_post_dispatch/]
 filter.

 {{{
 add_filter( 'rest_post_dispatch', function ( \WP_REST_Response $response )
 {
     $headers                   = $response->get_headers();
     $headers['X-Added-Header'] = 'Foo';

     $response->set_headers( $headers );

     return $response;
 } );
 }}}

 This filter provides the Response, Server, and Request object instances to
 the callback which should provide all the context necessary to modify the
 response as needed.
