* This is only necessary for default components using @Typed that want to support overriding.
 *
 * As a non-default component this now gets a negative priority relative to other implementations
 * of the same interface. Since we want to allow overriding this doesn't matter in this case.
 * (if it did we could add @Priority of 0 to match the priority given to default components.)

Once the ClassRealm has been populated and all Plexus components have been discovered a lookup can be performed to retrieve the primary plugin component. Currently the component would need to be looked up and then the BasicComponentConfigurator would need to configure the component with a given Plexus configuration. We will discuss later how we would retrieve the Plexus configuration required for a given plugin.
