i think it would make sence to hide the bundle-item in the cart views.
for example: you have a product bundle where the user could config the bundle components (products) himself, i dont want to see the price of the bundle, because the price gets callculated from the components and the bundle itself will be at € 0.
i think it could also make sence to hide all other items from the view expect the bundle-item.
for example: your products dont have there own price because the user could only buy them in combination with other products (as a bundle). so only the product bundle will get a price.
and sometimes maybe it only would be nice to hide only the prices from the "product attributes" field, but i will not think on an example this time.
