For me, the main concern is that the proposed implementation creates duplicate hwmon entries for the same device, which is simply messy. If both the kernel thermal mechanism and the userspace mechanism are needed, I think it would make more sense to use a thermal driver and have that thermal driver generate the necessary userspace events.
