Authoring in DSL can improve efficiency and productivity, but in my experience DSL itself brings benefits to a limited extent. It can be easier to read and write, but these benefits require one to understand the business model behind the DSL, which is usually more time-consuming. Having a strong validation and observation toolset based on the DSL brings more value than the language itself. DSL constrains its semantics so it is easier to build tools on it.
