It's always the race for more and more telemetry that seems to justify an increase in general data collection. Can't we just accept a certain level of blindness/primitiveness? More specifically I wonder, how has the addition of this collection approach improved whatever it's used for over the previous approach? Is that improvement worth it? Or is it, as is often the case, data for data's sake that makes them feel better about decisions than whether the decisions are actually any better?
