While they can change, in practice they don't. It's a useful way to
select sensors that several other projects support. I don't see why it
couldn't be supported by ipmitool as an option.
As a use case example, I've seen some motherboards that have duplicate
sensors w/ the same name, so you can't select a specific sensor via
ipmitool's current "get SENSORNAME" option. Here's one example of that
situation.
# ipmitool -I free sensor list

# ipmitool -I free sensor get Temp
Locating sensor record...
Sensor ID : Temp (0x1)
Entity ID : 3.1
