[Approval Request Comment]
Regression caused by (bug #):
User impact if declined: Smaller dataset to use telemetry for decisions
Testing completed (on c-c, etc.): Has been on beta for a long time now.
Risk to taking this patch (and alternatives if risky): Adds a data point to an existing telemetry probe, so I can't think of any risk to the user.
