CDK outputs CloudFormation templates that you can pass to any other tool if you wish. CDK is technically just a glorified shim over CFN (although 1000x better but you do get caught in the awkwardness that is CFN many times).
If anyone notices a problem you'll likely need to write a COE, there's no way to get around that. Not updating the status page absolutely doesn't get you out of that task.
COE also doesn't lead to negative marks on anyone at AWS that I know of. It's a learning experience to know why it happened and action items so it doesn't happen again.
