Yes, please! And it's not only important for the extra features as Rob mentioned, but it also should be integrated in payments / invoices, as in some countries (like Germany, for example) it's obligatory by law. All invoices have to have both addresses, of the business, and of the customer.
I could get fined if someone checks and I don't have this information on my invoices.
