Comment (by jeremyfelt):

 As @sc0ttkclark mentioned earlier in #core, something like `register_meta(
 'post', 'my_key', null, 'auth_callback' );` does not currently work as
 expected. Instead of adding the old auth filter and skipping the old
 sanitize filter, it adds no filter and returns a `WP_Error` about not
 providing an object subtype.

 [attachment:35658.37.diff] treats the old auth callback argument the same
 as the old sanitize callback argument. If it is provided and callable,
 then we should ignore that any array of arguments was passed. No tests yet
 for this.
