Hi,
Well, the thing is that you might not want to include the details of the bundle in the invoice/shipping invoice because you still handle the bundles as separate products and don't want to confuse the customer.
This means that if we were to add that, it would have to be an option as you don't necessarily want that.
For now, we're waiting for more feedbacks to decide what to do and what should be improved with the bundle system since it's something still pretty new.
So we don't have plans to add it, for now.
