----------------------------+-----------------------------
 When sending an update to a piece of content via the REST API, meta
 registered with `'single' => false` cannot be removed by sending an empty
 array; you must send `null`.

 The inability to send an empty array is slightly confusing and
 inconsistent with `array`-type meta registered with `'single' => true`,
 which will correctly save the empty value.
