I'm actually against this. You push all your stuff upstream -your 
management foundations- and you are dependent on the other stuff release 
schedules, and you don't have one single place to do your own layers, 
your own indirection.

This doesn't imply anything against commons-config, just that there is 
benefit from having some core stuff, and it's in management that it 
really wins, and in shared utility stuff like in-VM httpd servers
