I am not sure why the author thinks that DEBUG level is about debugging your code before putting it in production. The real use of DEBUG is in production when one day the roof is caving in and the normal logs do not have information for you to figure it out.

Especially when the deployment is not under your control. That is when you ask to enable DEBUG so system can spew more information and you can trace the execution better.

OTOH, this whole idea of attaching trace-id (Android) and where the log came from (modules and functions) is nothing new. on the whole, I am not sure what the takeaway is.
