Old Files notification on D8
A CiviCRM 5.25.* install on Drupal 8.8.* displays the status report message for the "old files" which should not exist. Ordinarily this message is helpful, because those files are in the web root and could be web-accessible. On d8 those files are outside the webroot (if using the recommended Drupal 8 install structure!).
This message cannot safely be actioned on D8 composer installs without causing composer errors due to changed dependencies. It would therefore require the upstream projects to stop shipping those files or CiviCRM to suppress the error on D8.
