Serverless Stack

So I've just discovered <https://github.com/aws/aws-cdk/tree/master/packages/%40aws-cdk/custom-resources|CDK Custom Resources> and they seem pretty cool. It got me wondering, has anyone used this before for more interesting use cases?

I see that you can run aws-cli commands with it (e.g. validate an SES domain), but I was wondering if people used it for stuff outside AWS, I can see it useful for creating resources outside AWS and use the results inside cdk.

the sst.Script construct is implemented on top of Custom Resources.

The best use case is for asynchronous integration tests using a step function. If the test fails, the deployment will rollback.
