IAM is not included in google-cloud-java project?

I was wondering whether google-cloud-java  includes IAM service as I found out that it is provided separated from this project based on https://developers.google.com/api-client-library/java/apis/iam/v1. I think it will be helpful for user to have centralized project for all of the services
