 * A side effect of using @Typed is that it translates to explicit bindings in the container.
 * So instead of binding the component under a 'wildcard' key it is now bound with an explicit
 * key. Since this is a default component this will be a plain binding of ModelProcessor to
 * this implementation type, ie. no hint/name.
