Comment:

 From [https://wordpress.slack.com/archives/core-restapi/p1489551197969063
 Slack discussion], this is working as intended.

 > Explicit is better than implicit

 I agree with this - the order should not change based on the query
 parameters.

 > if `include` is an arg, shouldn’t `orderby` be `include` by default?
 that’s how `post__in` works internally

 I'm seeing different behavior:

 {{{
 wp> ( new WP_Query() )->query( array( 'post__in' => array( 1, 5 ),
 'fields' => 'ids' ) )
 => array(2) {
   [0]=>
   int(5)
   [1]=>
   int(1)
 }
 wp> ( new WP_Query() )->query( array( 'post__in' => array( 5, 1 ),
 'fields' => 'ids' ) )
 => array(2) {
   [0]=>
   int(5)
   [1]=>
   int(1)
 }
 }}}

 I agree with this also:

 > If you mean other uses of `WP_Query`, matching the behaviour of that is
 not a design goal
