There’s basically no downside to adding the feature. But it really helps for playpens and notebooks and teaching. Playpens and notebooks want to focus on the example code in question and it’s good to hide the boilerplate. Teaching is vastly improved because the `main` boilerplate in hello world contains about four lessons worth of material (functions, classes, arrays, and namespaces) that needs to be handwaved to a class of beginners and if they screw up the magic incantations they get scarey error messages.
