We already have TOML and it's great. I can seamlessly upgrade from ini to toml.
TOML is probably my go-to these days.
I think where TOML shines is when your configuration schema is relatively flat and simple. If you want to heavily nest configuration it can quickly get difficult to read. I’d love a more limited version of TOML that restricts the nesting depth.
There's a comparison [0] where some differences are explained.
