Template writers lack the tools to build abstractions around the data. Layering Examples: kustomize Data layering breaks down when configurations grow in complexity and scale. Template writers lack abstraction and type validation. For large scale projects, inheritance creates deep layers of abstractions. Semantics are locked into an opaque tool and not exposed as language features....
