That told us where eval was still happening in the wild, including Mozilla code paths we didn't have tests for and, crucially, a thriving community of Firefox tinkerers using userChromeJS and friends. Because telemetry surfaced those scripts, I could go talk to that community, explain the upcoming change, and work around the breakages.
