I'm a bit worried about making this automatic, as it can have unexpected side effects on BigQuery load-job quota. This is a 24-hour quota, so if it's accidentally exceeded all load jobs for the project may be blocked for the next 24 hours. However if the user opts in (possibly via .a builder method), this seems like it could be automatic.
