I still prefer ini files for configuration. Easier to grep and sed.

You can get a bit more if you use TOML over INI... it's similar at a baseline, but still a bit more rich for advanced configuration than INI is.

My belief is that anything that requires more than that are hiding the fact that what they truly need is a DSL. Instead they force you to write AST (ansible, github actions, docker compose,…)
