libsensors supports that just fine since version 3.0.3 which was
released in September 2008, over 5 years ago.

Applications bypassing libsensors are on their own, and always have
been. But several other drivers have had their attributes in the hwmon
device forever so even these applications are likely to be happy with
other drivers moving in that direction.
