Comment:

 The function states that it the $list parameter is an array that contains
 arrays or objects:

 {{{
 /**
  * Pluck a certain field out of each object in a list
  *
  * @since 3.1.0
  *
  * @param array $list A list of objects or arrays
  * @param int|string $field A field from the object to place instead of
 the entire object
  * @return array
  */
 function wp_list_pluck( $list, $field ) {
 }}}

 It does not state that it operates on an array that contains referecens to
 other arrays.

 As well as it doesn't state that it operates on an array that contains
 references to other objects.

 That's not what it has been made fore. So why do you expect it to be
 working with references?

 And if it is expected to be working with references, shouldn't it return
 references then?
