General question regarding this, would it be a good idea to wrap the AWS SDK with the credentials provider to do this job? This has been my current workaround for this issue and might be a better long-term solution for managing all the various ways you can authenticate with AWS.

Thanks for the suggestion. We previously had a discussion here: #139.

The various methods for authentication are limited and rarely change, so we can ultimately support them all. I believe it isn't worth introducing the AWS SDK for authentication.
