Description

With Logback its possible to use ChangeLevelDispatcher [1] to minimize the performance impact. Currently one needs to explicitly enable in logback.xml via

<configuration>
  <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator"/>
</configuration>

It would be better if Logback Integration logic adds this listener on its own if the org.apache.sling.commons.log.julenabled is set to true without requiring explicit user effort to tweak Logback xml config
