Ceki Gülcü commented on SLF4J-124:
----------------------------------

Obviously, SLF4J made a distinction between levels in {{org.slf4j.Logger}} about levels via printing methods such as {{Logger.debug}} {{Logger.info}} etc. However, until relatively recently, SLF4J did not have {{Level}} defined a distinct class/enum. This will change in 2.0 which introduces the notion of a piecemeally constructed {{LoggingEvent}}. 

As such, it makes sense to support logging at dynamic level.

> It is occasionally useful to have a log method that takes a level as a parameter.  The necessary methods can be added to the Util class without any compatibility issues as far as I can see - see attached patch.
