The concept is awesome but it's curious to see YAML at the core of this project, rather than a Turing-complete, embeddable language like Lua.

YAML is "good enough" for a vast range of tools. It's a good thing that these maintainers are focusing on their core competency/goal of the project and not pandering to niche HN opinions on the stuff that doesn't matter.
