ArduinoOTA as well? Even a failed update kills every client
Also note of WebUpdate example

Continuing the idea, UpdaterClass should probably handle that

	//This callback will be called when OTA connection has begun
	void onStart(THandlerFunction fn);

	//This callback will be called when OTA has finished
	void onEnd(THandlerFunction fn);

	//This callback will be called when OTA encountered Error
	void onError(THandlerFunction_Error fn);

	//This callback will be called when OTA is receiving data
	void onProgress(THandlerFunction_Progress fn);

Where the user might as well do the

WiFiClient::stopAll();
WiFiUDP::stopAll();

// or, where we want some fine grained control
WiFiClient::stopAllExcept(&server.client());
WiFiUDP::stopAllExcept(&myPreciousCnC);
