#needs profiling

Core is currently doing for /system/files/ route.

It uses an InboundPathProcessor to get the route of the file, set it to a query parameter and return just the /system/files to allow the route system to match the route, no matter how many / the file has, because now is in a query parameter.

class PathProcessorFiles implements InboundPathProcessorInterface {

  /**
   * {@inheritdoc}
   */
  public function processInbound($path, Request $request) {
    if (str_starts_with($path, '/system/files/') && !$request->query->has('file')) {
      $file_path = preg_replace('|^\/system\/files\/|', '', $path);
      $request->query->set('file', $file_path);
      return '/system/files';
    }
    return $path;
  }

}

Then, in the controller, it gets the target by accessing the file query parameter.

    $target = $request->query->get('file');

Thank you for creating this issue to improve Drupal.

We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!
