Not sure we want to change it. Mixing PID and CPU into the same 
space disallows the simultaneous application of both. I.e. right now 
we allow 3 models:

 - PID-ish
 - CPU-ish
 - PID and CPU [say measure CPU#2 component of an inherited workload.]

Also, i dont really see the use-cases for new targets. (i've seen a 
few mentioned but none seemed valid) What new targets do people have 
in mind?
