I know XML is very last century but if they could coexist in one file, a file that treats each config section as an object, so we can create a Project Object Model, call it pom for simplicity, and then if you are old store it in xml and the you could have only one file and call it pom.xml and then maybe one day someone can make this very useful file a bit more modern and turn it into json or yaml but for now a single pom.xml could save us from that config hell others speak of /s
