It avoids the whole set of issues you get with templating yaml with helm since its structure aware.

Also you can actually write pure code libraries in starlark (basically a subset of Python)

I'm aware, but I just don't understand the point of it. How is it in any way better than a purpose-specific configuration language like Dhall/CUE/Jsonnet? What's the point of having it look like YAML at all?
