We have developers of various experience and skillsets that come and go, sticking to a subset of language features with minimal magic has made it easier to onboard and get people productive. We have massive codebase, and sprinkling these new sugars around in arbitrary places to be lindmines for them isn't worth it to me. From a business perspective, we're not too concerned about pushing the language forward, we're focused on creating value for our customers - the language is just a detail.
