I'm not up on the logging tips and tricks best practices these days,  
but yeah, I was suggesting something like that.  There's no rule that  
says logging keys be FQCNs.... that's a decent convention for most  
cases with a package structure that is well organized and filterable.   
In this case having the core name in there as a prefix makes a lot of  
sense to me.

We could provide a LoggerUtils.getLogger(core, clazz) or something  
like to keep it DRY and consistent.
