 This extra trait is an implementation detail that is not in the public-facing, API so it can be migrated away when support for AFIDT is introduced.

 The SDK uses this same idiom several times:
-* `ProvideCredentials`: https://docs.rs/aws-credential-types/0.54.1/aws_credential_types/provider/trait.ProvideCredentials.html
-* `AsyncSleep`: https://docs.rs/aws-smithy-async/0.54.3/aws_smithy_async/rt/sleep/trait.AsyncSleep.html
-* `ProvideRegion`: https://docs.rs/aws-config/0.54.1/aws_config/meta/region/trait.ProvideRegion.html

 ## Future improvements
 
-With AFIDT, we can drop the `ProvideCredentialsDyn` trait and just use `Box<dyn ProvideCredentials>` as is. Refactoring the API to use AFIDT is a totally internal-facing change.
