Details

Bug 1494473 added Baseline support for tracking the effectiveness of IC chains. It would be nice to be able to see similar results for IonScripts. It may be useful to have this even for Ion scripts to allow us to build feedback mechanisms about cleaning out the IC chain, and would be useful for showing when IC chains aren't performing as we expect (i.e. every query hits the fallback IC).
