I'm still on the fence (and distracted by Vision Pro). It's a good-ish idea, IMHO. I'd like to see a toolkit for "reading configs" where configs are some universal format (JSON, YAML, TOML, etc) for various languages. So that the app in Ruby can share config with "microservice" in Rust and they can also maintain compatibility with completely different app (but sharing infra resources) in Go. Using one config language that supports hierarchical templates, modules, imports, whatever. Because otherwise everyone starts inventing their own "YAML with functions", "JSON with templates", etc. Pkl seems like that. But I don't like that it's Turing complete. Powerful and dangerous. Configs are inherently declarative.
