My point was that the current config file formats are not good enough - I agree with that - but if we want to switch away from them, we need even better formats. They need to be at least good as the previous generation (XML), which had schemas. JSON and YAML are a regression which became popular because of their simplicity.
We need the simplest config format that comes with a schema. They should either come with a separate schema system or with a type system that is powerful enough to implement what I said before: regexp validation, interval validation. Without making you write more than validate="[a-z]*", not writing a whole class or such.
