How are INI files used today? [closed]

I really like the "INI" file format: Declarative KEY=VALUE, possibly embedded in named sections.

Further, I like the old "Make" style, where values set "higher" in the file may be interpolated into values "lower" in the file. (I know that's not specifically INI style, but Makefiles behaved largely like INI files for values, which I liked, to centralize maintenance of values.)

This is still a popular file format for configurations, right? If you were writing new tools today that relied upon configuration files, you'd use INI files, right? How are INI files being used these days?

No, I wouldn't. YAML (to choose one of many possible examples) is as concise as INI while giving your configs arbitrary depth (unlike INI, which gives you only two levels).
