Vscode already supports linting yaml against a schema file. Once you start configuring your code with configuration-as-code, you’re just writing more code.

If I need to “generate” some insane config with miles of boilerplate, I would use js to build my json, which can be ported to just about anything. This would replace js in that process.

I’m not sold on the need for this.

Even with something like k8s, I’d reach for pulumi before I put another layer on top of yaml.
