The point of this is to lower the entry cost of producing interactive CLI apps. If I have to break out a more expressive language to use it I may as well just write my program in that language in the first place.

There are other config formats that provide this and don’t rely on sometimes ambiguous whitespace based structure (eg. TOML). While you can write JSON in a YAML file to avoid this, you’ve then nullified all of the supposed ‘benefits’ of YAML.
