mod_external_services: Report overall status as a module status Because during startup, if all items are provided by a different module (e.g. mod_turn_external) then this would log a scary warning even if everything is fine after that other module has been loaded. This way, any persistent problematic state is reported in the console. Errors with individual items should still be reported by prepare(). Now, if you load mod_external_services alone without configuring any services, no error or warning is reported in the log, but maybe that's not so bad with it reported in the console.
