No, nlog4j is not marker ready.

It's a useful idea which needs to be validated by a real implementation.

No such implementation exists which is the reason why the Marker interface 
is no longer present in later released of SLF4J.

No, Markers have nothing to do with AOP. They can be used in any 
environment. I hope to come up with an implementation sometime in the near 
future.
