Always enabling is good but just wondering if it has any side effects. Otherwise 👍

The side effect is that users in the community will be able to get from buckets in other S3 regions even if they don't want it. I think this should not be a concern. I looked into the authentication approach and it doesn't make multiple STS calls. It uses only the one STS session and uses that in different regions. I also verified this using the AWS SDK request logging. Also, it caches the bucket to region mapping so it only makes two requests once. |
