> yml/json configurations for [...] We learned this lesson the hard way with XML back in the early naughts when behind everything was a nauseating morass of xml with overcomplicated designed-by-committee schemas. People moved out of development and tried hard to forget it, but neglected to instruct the next generation about the pitfalls of shitty configuration files that get out of control. Now we got json and yaml. No more </>'s, yay, but somehow worse, less maintainable and less understandable.
