Processed metrics metadata 

Then to keep the system manageable and not full of arbitrary branches (ie, if we do this report, let's only serve 3 metrics, but in that report let's serve 6, but in this other report, let's serve 4, but in this last one let's serve 6 + 2 that were hidden) we should show the metrics everywhere. What does it matter if someone who doesn't need them sees them? Especially if that someone is a machine consuming API output.
