 Replying to [comment:4 flixos90]:
 > So which of the two is right? Should `register_rest_field()` callbacks
 accept an object or an ID?

 They should accept an object.  See the first code example at

 It sounds like the unused `WP_REST_Meta_Fields::register_field()` method
 was never tested, and it should be updated to accept an object.  Also, we
 need to improve the `register_rest_field` documentation to indicate the
 types/signatures of the values accepted by its `$args` argument.
