It's not really astonishing. People don't usually have knowledge beyond a quick google search. If you google XML, you'll see a lot of negative sentiment about XML specifically related to mid-00s Java frameworks and some people chunk this fact as "XML old and bad". If you google YAML, you'll see that lots of people like using it for relatively simple things (Rails config files...) and some people will chunk that fact as "YAML good".

For me, one of the true advancements of JSON/YAML over XML is how its features are orthogonal to each other I don't have to ask "should this be a tag property, or a subtag"?

Which, to your point, isn't to say that YAML is "good", but I think there was at least an advancement through minimalism.

Right tool for the job. I think XML is too much tool for most jobs, but there's a huge gap between JSON/YAML and XML, so in 99% of cases I'd rather err on the "too much" side.

defo agree, mate. if data that is consumed by computer is really crucial, I'd better be sure to use any format that has clear AST, schema, or whatever ya call it. now I'd rather use xml / clojure's data sexpression / even json over yaml. it's just a gut feeling, in the most part.

YAML and other human-friendly presentation/editor formats are cool, but they need to come with a schema/validation/types. k8s APIs have a bit of validation, but there are frustrating gaps.
