JSON and YAML are incredibly common for config files for newer software.
I've not really seen YAML used as a data interchange format, in my
experience it exists almost entirely to be a more human-friendly
alternative to JSON for configuration.

The Java properties file format is well-defined and, not surprisingly,
used heavily by Java applications. I've been out of the Java world for a
while, but in the 2000s, properties files were definitely in use for
configuration files for many applications I ran and worked on.
