This package now references "EC2 Instance Connect" as a replacement: https://aws.amazon.com/blogs/compute/new-using-amazon-ec2-instance-connect-for-ssh-access-to-your-ec2-instances/
However there's one component I don't see in 'EC2 Instance Connect` - the bulk import of IAM users into local users onto the AWS linux instance.
Is there some other mechanism that is intended to handle that function?
