The migration style changes sound really interesting.

CDK indeed is just another layer of abstraction on top of CloudFormation, itself already a leaky complex abstraction, and it bites you in a lot of ways.

Same could be sad for Pulumi though, couldn't it? It's a leaky abstraction on top of Terraform which is a leaky abstraction on top of $YourProvider's API.

I'm still much happier using CDK vs CF or Pulumi vs HCL though.

the problem isn't necessarily in the abstraction. It's in the language design. Terraform (HCL) started off as a declarative language. Then people wanted string concatenation. Then conditionals. Then modules. You end up with this kludge of a language that benefits from none of the foresight of having been designed as a general purpose programming language from the outset -- no unit testing, poor control structures, etc.
