I think INI files are often better for anything that will be hand written. Once you start adding layers of nesting the semantics themselves get confusing and people get tempted to reorganize things. Flat is Better than Nested, says Python. JSON is great for machine to machine stuff that a human might incidentally modify or debug. For anything else, there's other formats. Although multiline strings are nice to have. Seems like a decent approach might be the robustness principle. Accept it, and if support becomes really common, them start writing it? This lacks unquoted string values though. I'm not sure why being a subset of ecmascript matters aside from just consistency for the programmer?
