It could be useful if you want to prompt a user to reboot their phone because something isn't working and a reboot often helps. But if they just rebooted, telling them to reboot if they've just rebooted is going to annoy them for no reason.

Things like the user gave permission for camera or microphone and is trying to use them but there's no data coming through. Or really most anything with Bluetooth. Or sometimes their mobile network is being weird.

That probably doesn't justify sending it off the device as a raw value, but Meta really likes driving UI from the server instead of letting the phone be smart. And they have a habit of pushing Apple's limits.
