Actually I used to recommend looking there when people were not using libsensors (e.g. for pwmconfig / fancontrol or custom scripts.) This path had the great merit of being stable across reboots, while hwmon class device numbers are not (or at least they aren't guaranteed to be.)

I am just realizing that we are also losing the stability of hardware device based paths with that move :( I suppose I shouldn't have bothered adding support for this to fancontrol.
Don't get me wrong, I still believe this is the right move, but I fear that the question of persistent hwmon device names will resurface every now and then again. libsensors offers a solution but 1* it lacks support for pwm attributes and 2* it doesn't help with shell or perl scripts such as pwmconfig and fancontrol.
