Cloudstor Status

Our company makes an intensive use of docker on AWS, we are using cloudstor to manage persistent data with EBS/EFS and it works fine.

However, we are now in need to use encrypted EBS/EFS and there does not seem to be any plan to extend cloudstor to handle encrypted drives, there is an open issue in the gitlab for almost a year now : https://github.com/docker/for-aws/issues/159

Actually there does not seem to be any plan anywhere for the future of cloudstor, so I am asking what is the status of this plugin ? Is it still maintained ? Are new features scheduled ? Actually all those questions holds for the entire docker-for-aws. Is it possible to have an answer from the docker team ? If the plugin is not supposed to be maintained, will the code source be released at some point so we can expand it ?
