I don't quite follow you... what would that reason be?

Well, the driver posted by Lu was rather small, and most of it is for
device management, not functionality. Adding temperature reading to
another driver would probably fit in 250 lines.

Just because something isn't there doesn't mean we don't want to
implement it. Maybe nobody had the need so far.

A quick grep reveals these drivers:
But there may be other drivers which do export temperature readings
without registering a proper hwmon class device.
