You can setup dependent stacks in CDKTF. It’s far from as clean as a standard TF DAG plan/apply but I’m having a lot of success with it right now. If I were actively using k8s at the moment I would probably setup dependent cluster resources using this method, e.g: ensure a clean, finished CSI daemon deployment before deploying a deployment using that CSI provider :)
You're right that CDKTF with dependent stacks is probably better than nothing, but (a) CDKTF's compatibility with OpenTofu depends on a lack of breaking changes in CDKTF, since the OpenTofu team didn't fork CDKTF, so this is a little hairy for building production infrastructure; (b) CDKTF stacks, even when they can run in parallel, still run on the same machine that invoked CDKTF. When you have (ludicrous scale) X number of "stacks", this isn't a good fit. It's something that should be doable in one of the managed Terraform services, but the pricing if you try to do (ludicrous scale) parallelism gets to be insane.
