I think, for any language that "targets the Golang runtime", you do need some way to express to the runtime to "use the zero-value default initializer." Otherwise, you'd have no hope of code in your language being able to be used to define e.g. protobuf-compatible types; or of using Golang-runtime reflection (due to e.g. the interface zero-value.)
