Comment (by grapplerulrich):

 @kadamwhite Thank you very much for committing this. I have ended up
 backporting this commit for WP 5.2.x so that I can use this feature before
 5.3 is released.

 Though I got a PHP notice:
 {{{
 Undefined index: items in wp-includes/rest-api/fields/class-wp-rest-meta-
 fields.php on line 554
 }}}

 https://github.com/WordPress/WordPress/blob/master/wp-includes/rest-
 api/fields/class-wp-rest-meta-fields.php#L554

 I think the reason for this PHP notice is that `items` is not defined in
 `$default_schema` in `get_registered_fields()`.

 My code that I used:
 {{{#!php
 <?php
 \register_meta(
         'post',
         'swisscomkbw-authors',
         [
                 'show_in_rest' => true,
                 'single'       => true,
                 'type'         => 'array',
         ]
 );
 }}}

 The inline documentation still needs to be updated for the support or
 arrays and objects in `register_meta()`

 includes/meta.php#L1126-L1127
