The main reason for viewbox to exist is that there are many cases where we don't want the viewbox to cover the entire graphicsview -- for example, when making space for axes/labels, or when we have multiple view boxes per graphicsview. As you have found, one downside to this approach is that the nice shared-scene feature of graphicsview becomes useless.
I agree with Patrick that usually just duplicating items is the easiest way to go here, but in the rare cases where duplication is not an option, then using bare graphicsview is a reasonable solution.
