I just saw some discussion in the IRC by GunnarM quoted as:

> /sensors is sensors that aren't in Power/Thermal https://redfishforum.com/thread/190/sensorcollection-contain-all-sensors-chassis
> For 2020.4 this changes, all sensors will be under /sensors with only a link to the Power/Thermal/Fan/Powersupply schemas

But from the Redfish spec it does not say /sensors should exclude the
ones in Power/Thermal, instead /sensors is "the link to the collection
of sensors located in the equipment and sub-components".
So I am expecting that it should contain all the sensors in the system.
In OpenBMC, this could be done by returning all the objects that
implement the xyz.openbmc_project.Sensor.Value interface.

@Ed Tanous @GunnarM Could you kindly provide some comments?

Thanks!
