This is a duplicate of boto/boto3#3889. As mentioned there:

The team is aware of this issue and working on addressing the warnings. These deprecations won't cause impact currently beyond the warnings. The required changes are not fully backwards compatible for existing usage. We'll be prioritizing a more robust fix in an upcoming release.

Closing to continue tracking in that issue.
