well, now I assume you mean 1.0. Techinically Arduino is still in beta
Actually I meant 2.0 because the roadmap to 1.0 is been already planned. Those feature should come after 1.0 has been released.
Its true that it will take away a big creativity part, but it doesn't means you must use it. In certain cases it could be interesting to try something without unmounting your arduino.
And maybe Fritzing could use a feature to create instruction on how to mount your board after you have finished virtually building it.
Also could be used to virtually test components and see what their normal behaviour is and find our broken components.
Also sharing a project between more developers could be made easily.
