I wouldn't take my particular use case as evidence they are common, or even they really exist. I got here because I loaded a hwmon driver using the _DSD/PRP0001 mechanism in ACPI. In that case, those devices have never worked with 'sensors' Therefore, in that context, this change is just fixing a bug. I can't say much about other apps writing against the current sysfs names. 18 months seems like a long time. --Dustin
