It can't be DRY and modular with CDKTF though - you can't really put components into Go modules, for example, so, you still get a monolithic codebase unless you use Go as glue code and put all the IaC in Terraform modules. I think Pulumi is better in that regard and those who don't want to use a programming language can use the new Pulumi YAML. I do use CDKTF where Terraform lacks: dynamic providers and dynamic resource names. For anything else, modular Terraform code does that and does it better, and it's more readable and works with the existing Terraform ecosystem of Terraform Cloud, linters, security scanners, drift detectors, etc.
