If you want a tool to be able to generate executable validation from a schema, a compiler framework should come in handy. It seems like they did not aim to make yet another mvp configuration language, but something that can scale across a wide range of usage scenarios spanning all the way from short-lived processes reading a number from a file to huge libraries of default/override hierarchies. Lack of universality sets an upper bound for the value of a configuration language, particularly when seen through the lens of configuring heterogeneous tech stacks.
