Civicrm settings still require group for mandatory overrides???

Our docs say group & groupname are fully deprecated here

https://docs.civicrm.org/dev/en/latest/framework/setting/

but they are still documented as being required for overrides in civicrm.settings.php & I think they are still needed if doing an override here

https://docs.civicrm.org/sysadmin/en/latest/customize/settings/

@totten you can probably confirm.... Perhaps it's just

$civicrm_setting['antyhing works here ']['customFileUploadDir'] = '/var/www/testing/sites/default/files/civicrm/upload';
