Honestly I don't... YAML is more compact but still hyper verbose and hyper rigid respect of XML witch is the same respects the older SGML. The old new trend is going through real programming languages instead of dedicated data-formats, from those who use Python or DHall or those who prefer lisp to be in a more civilized land... Just compare Ansible/Salt YAML+python (because you can't do anything YAML-only) to Guix System, just see k*s YAML or Home Assistant ones: they are horrible to manage by a human. They are not much effective respect of anything else for a machine. Long story short IMVHO it's about time to recognize that the old "data and language together" is the way to go, erasing common DSLs/formats/parsers etc.
