Instead of doing review comment I spent time doing a branch at: https://github.com/vivien-apple/connectedhomeip-1/pull/new/YAML_TestSubscribe

The branch does not support Darwin at the moment, it still needs to be done.

In my understanding the following block could also be remove if a method to remove the reporting callback is added to the tree ?

        if (runner->mReceivedReport_{{index}}) {                                                                                                                                  
            // Receiving report more than once is not an error since the subscription may be alive for a long time.                                                               
            ChipLogProgress(chipTool, "Note: on report called more than once.");                                                                                                  
            return;
        }
