Hi Nikolay,
there is no special use case here. It was just my laziness/curiosity regarding the evaluation of log files. When diagnosing errors in an app one may has to repeatedly change, package and redeploy it. If this happens in an iterative manner and with some detailed logging level like debug one will quickly get a large log file which isn't a pleasure to analyze. This is the only reason for my question so I don't think its really a requirement. And since I've found the error in my app there isn't even a reason for my question any longer ;-)
Best regards,
Tobias
