Is the type "Configuration" ever used in the current json API?
Its listed but I can never find its use.

"Configuration": {
"id": "Configuration",
"properties": {
"notifications": {
"$ref": "Configuration.Notifications",
"required": true
}
},
"required": true,
"type": "object"
},

Yes it's the return type of the JSONRPC.GetConfiguration request which is only available on transports that support notifications so WebSockets and TCP.
