This is a very good question and one to check - merely having crash logs disabled (at least for an HN audience) isn't a high information signal.

I've got crash logs and as much analytics and telemetry disabled in a custom provisioning profile just to save having to navigate through menus to turn everything off...

Would need to test this on one of those devices to see if there's a false positive as a result though. But it's possible this is a false alarm if it's just checking for existence of this file. Has anyone checked through the logic the tester uses?
