CloudFormation Changeset Workflow - EarlyValidation

Accelerate infrastructure development with CloudFormation pre-deployment validation and simplified troubleshooting | AWS DevOps & Developer Productivity Blog

The above feature appears to be in use, as CloudFormation runs detected failures from the changeset worfklow:

The following hook(s)/validation failed: [AWS::EarlyValidation::PropertyValidation]. To troubleshoot Early Validation errors, use the DescribeEvents API for detailed failure information.

However, it would be more useful if Deployment Validation failures were displayed along with this using the DescribeEvents API as mentioned, so then the developers did not have to try to track these down in the AWS console.
