Rclone is a magic tool, I've used it for many different use cases.

When I last checked it doesn't use the AWS SDK (or the Go version is limited). Anyway, it isn't able to use all settings in .aws/config.

But it is kind of understandable that it doesn't support all backend features because it's a multifunctional tool.

Also the documentation is full of warnings of unmaintained features (like caching) and experimental features. Which is a fair warning but they don't specifically tell you the limitations.
