Min , Max EIRP - usage?

When i create the device profile, there is a field to put in max and min eirp of the device. Even when I leave it untouched, devices continue to work. What is the purpose of these values?

It is currently unused by LoRa Server. However, as it is part of the device-profile as specified by the LoRaWAN Backend Interface specification, it is recommended to use the correct value when it will be used in the future.

@brocaar Is this available now or you are planning it for future? Is there any feature on network server to control gateway power levels or EIRP?
