Hanlon's Razor only stretches so far. It's become an established pattern of hiding a feature over next to the telemetry switches, explaining that they'd measure the results with lazy load telemetry - gently defining an unspoken void that's shaped a lot like "well if they wanted the feature maybe they shouldn't have turned off telemetry?".
