introduce PseudoKernel.
PseudoKernel allows Drupal's bootstrap to be treated as a service, which means it can be injected into dependencies so that Drupal can be only bootstrapped as needed when the request is not a Drupal route. Bootstrap now depends on the event dispatcher so that events can be triggered before and after bootstrap phases.
