I let other people comment if the hw.sensors tree should be consistent with the rest of the sysctl tree (personally I lean towards this, but I'm not interested in a bikeshed discussion, I just want to point out the current facts in FreeBSD) or compatible with OpenBSD (I don't moan if this is the final result).
