scala - Use logger after task completion using sbt 1.4.x

Question

Starting with sbt 1.4.x it does not seem possible to log using streams.value.log logger anymore after the associated task is completed (more details at sbt/sbt#5731).

This is used by the scalajs-bundler sbt plugin to log outputs from webpack-dev-server even when the task is complete. I found a global logger available under state.value.globalLogging.full fixing my issue, but as there is not too much documentation about it I am not sure it is the correct fix for my use case. Can someone validate the fix or point me to some documentation please?

Note: it is possible to fix the issue using ThisBuild / useLog4J := true (to use pre sbt 1.4.x loggers) but it is leaking large amounts of memory.
