Describe the feature

AWS has been sending notices about the pending EOL of Amazon Linux 2 in AWS Batch Compute Environments for a few times, see e.g. https://docs.aws.amazon.com/batch/latest/userguide/ecs-al2-ami-deprecation.html

The default is still AL2, though: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_batch.ManagedEc2EcsComputeEnvironment.html#images

Shouldn't the default be the non-deprecated image, especially for new environments?

Use Case

I'm frustrated when maintaining and creating Batch Compute Environments due to having to specify the machine image type manually.
