Yaml is on the way out, Cuelang will replace it where it's used for infra. It's quite easy to start by validating yaml and then you quickly realize how awesome having your config in a well thought-out language is!
well, then perhaps the growing frustration with a configuration language where meaning depends on invisible chars is an argument. And then what helm and others are doing text interpolating and add helpers for managing indentation.
There are many experiments into alternatives happening right now, so I do believe yaml's days are numbered. I'm actively replacing it where ever I encounter it with a far superior alternative. Cue is far more than a configuration language however, worth the time to learn and adopt at this point.
