You're missing the part where people do this periodically and can never truly remember all the gotchas so they make small mistakes with time that at one point make your cluster fall over with cryptic error messages. I've seen it (but as I said above I am by no means a k8s pro). That's why there are these linters. Having a small super-specialized language that catches errors before "compiling" your configuration to an YAML will help hugely.
