By not convinced, I mean that I am not persuaded by your approach but I am also 
not dismissing it.

You can use filters to create rules of action. Such filters can scan for message 
codes and when a particular message code is detected, the filter can modify the 
level associated with a logging statement. So, when you write

   logger.warn("The earth is warming up");

the filter can reduce the logging level to DEBUG instead of WARN on the fly. 
Filters can be defined in a configuration file which can be loaded and reloaded 
at will.

So, filters are another way of changing the logging level at runtime.

I hope this sheds some light on the matter.
