I discovered the 'validate' argument just recently. My concern was not costs, it was latency and response times. My server is generating a HTML page with signed URLs to resources on S3. The 'get_bucket' call adds a bit of latency as it contacts S3 and I was thinking, does it really need anything from S3 to generate signed URLs if I already know the exact key names, and am pretty sure the bucket exists? Well, it does not, and adding "validate=False" speeded up things noticeably.
