Hi All,
I searched for an easy way to display meta-box content created by Piklist in the rest_api response.

For example:

//Title: Custom meta to show in Rest
 //Post Type: post

piklist( 'field', array(
	'type'       => 'text',
	'field'      => 'custom_text',
	'label'      => 'Custom text demo',
	//'show_in_rest' => true, //not working :(
) );

I can use register_rest_field to add the meta to the api response ( for example : )

	register_rest_field( 'post', 'cm', array(
		'get_callback' => function ( $post ) {
			return get_post_meta( $post['id'], 'custom_text', true );
		},
		'schema'       => array(
			'description' => __( 'Custom piklist text.' ),
			'type'        => 'string'
		),
	) );

and it does the trick, but it would be awesome if just passing 'show_in_rest' => true to the meta params make it automatically show in the response.
