Yeah, by data-driven I mean the 
phosphor-ipmi-sensor-inventory%/config.yaml files in the openbmc repo 
where a sensor is matched to a D-Bus object. For example if we create a 
property under the Settings D-Bus object for the derating factor sensor, 
and add this object to the ipmi config.yaml file, a Set Sensor would be 
able to change its value, unless the host-ipmid read-only support 
prevents this. What is the read-only support in ipmi?

Thanks, will take a look, since we want read-only properties in 
sdbusplus regardless if they'll be used by ipmi.
