 * For a request the response should be an error with `code: -32002`. The message can be picked by the server.
 * Notifications should be dropped, except for the exit notification. This will allow the exit of a server without an initialize request.
 
-Until the server has responded to the `initialize` request with an `InitializeResult`, the client must not send any additional requests or notifications to the server. In addition the server is not allowed to send any requests or notifications to the client until it has responded with an `InitializeResult`, with the exception that during the `initialize` request the server is allowed to send the notifications `window/showMessage`, `window/logMessage` and `telemetry/event` as well as the `window/showMessageRequest` request to the client. In case the client sets up a progress token in the initialize params (e.g. property `workDoneToken`) the server is also allowed to used that token (and only that token) using the `$/progress` notification sent from the server to the client.
