AWS Fargate Spot - Automated Draining for Spot Support

Question

Does the recently announced AWS Fargate Spot support Automated Draining for Spot Instances running ECS Services?

I would assume yes, but didn't see anything definitive on that in the announcement blog post.

With Fargate there are no instances to be concerned about, so hence no need to worry about draining any instances. A Fargate Spot task will receive a 2-minute warning if Spot needs the capacity back. This notification is described in the documentation here:

https://docs.aws.amazon.com/AmazonECS/latest/developerguide/fargate-capacity-providers.html#fargate-capacity-providers-termination

The ECS on EC2 Spot scenario is different as it is the container instance that's the Spot capacity and that whole instance needs to be drained from running tasks. The ECS on Fargate model is much easier.
