 Within WP_Query::get_posts you find:

 {{{#!php
 // Convert to WP_Post objects.
                 if ( $this->posts ) {
                         $this->posts = array_map( 'get_post', $this->posts
 );
                 }
 }}}


 This costs a lot of time when fetching a lot of posts (e.g. products,
 orders, etc).

 It could be fasten up by fetching only the field "ids" but this is also
 bad because when we need the post_content then a "get_post( 123 )" would
 do another query.

 To bypass all of this a new "fields operator" could be added:

 {{{#!php
                 if ( $this->posts && $q['fields'] !== 'raw' ) {
                         $this->posts = array_map( 'get_post', $this->posts
 );
                 }
 }}}


 The SQL-Query would still fetch all data but we would prevent the data
 from going through the "get_post" stuff.

 In times of Generator it is ridiculous to iterate over the same set of
 data multiple times. By receiving the raw data the developer can decide
 when to generate a WP_Post object.

 Note:
 filter = "raw" could imply "suppress_filters" = true because we no longer
 carry WP_Post objects. But it should be allowed by the developer to switch
 "suppress_filters = false" again because the stdObjects have almost the
 same structure as WP_Post objects. This means (in short):

 {{{#!php
 if ( ! isset( $q['suppress_filters'] ) ) {
                         $q['suppress_filters'] = ($q['filter'] === 'raw' ?
 true: false);
                 }
 }}}
