Only if you want to include the metric in the V2 protocol. Then you need to extend the protocol (messages may grow by new fields) and probably modify the server
and clients to also parse and display the new data.

There are lots of new metrics in V3 that are not covered by the V2 protocol and probably never will. The V2/MP server is included for compatibility, next level
development may focus on V3/MQTT. MQTT isn't fixed to message formats and can transport all metrics.

Tom, Robins changes are only on the Leaf module, nothing relevant to the framework. Can you have a look?
