Informing users for BigQuery Storage Read API pricing differences

[botan]

As downloading tables using the BigQuery Storage Read API will become the default option if the bigrquerystorage package is installed, I was wondering if it would be helpful to mention the pricing differences between the BigQuery API and the Storage Read API. AFAIU from the official pricing documentation, although the Storage Read API is significantly cheaper in terms of query billings, it may lead to high network usage charges for transferring data across regions.
