Comment:

 I looked at all the usages of `add_additional_fields_to_object` and
 `update_additional_fields_for_object`

 As far as I can tell, the REST API always passes an `array` to the
 `get_callback()` and always passes an entity object to the
 `update_callback`.

 > An object will still be passed, sometimes, too.

 Could you clarify when this happens?

 Perhaps this has been fixed in the meantime?

 The documentation certainly could use updating as well.
