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?
