If you put the diffuser dome on upside down, it doesn't cause the gun to default to the wide setting and you can continue with the gun zooming with the lens. I'd find this useful if I just want a diffusing filter, while keeping the gun working with the focal length of the lens.
Can't see how it would harm the flashgun but take this as my disclaimer anyway.
