Comment (by jeremyfelt):

 I think the REST API chain looks like this:

 1. Meta is either protected or not protected via the application an auth
 callback or with a `_` prefix.
 2. Both protected and not protected meta can be registered for automatic
 inclusion in a REST API meta endpoint via `register_meta()` with
 "show_in_rest".
 3. If a meta key has been registered with "show_in_rest", it will appear
 in the JSON Schema for the object. If the user is authenticated,
 information on protected meta will also appear in the schema.

 And then:

 * If a meta key has been registered with "show_in_rest", it will be
 available via `REST_API_URL/post/123/meta/`
 * If a meta key has been added as a custom field in
 `register_rest_field()`, it will be available as a property in
 `REST_API_URL/post/123/`
