I probably phrased my question poorly. Why would I use a tool which is not or poorly maintained for a probably already outdated version of a specs, when I can use something else, that has been used for years by countless companies in productions? The advantages must be huge. And I don't know what they are.
OpenAPI is another example. There are threads on hacker news about generating code from OpenAPI specs. These always seem to say "oh, yes don't use tool X, use tool Y it does not have that problem, although it also doesn't support Z". The consensus seems to be to not generate code from an OpenAPI specification but to just use it as documentation, since all generators are more or less broken. Contrast that with for example JAXB (which is not an exact replacement I know), which has been battle tested for years.
I've used jsonschema and it was fine. I didn't think it was poorly maintained. By contrast with most XML libraries I've used had a myriad of broken edge cases and security vulnerabilities brought on by its overcomplication and the maintainers' inability to keep up.

OpenAPI still functions just fine as a means of documentation and validation.
I'm allergic to all forms of code generation, to be honest. If there is an equivalent of XML in this I imagine it's even more horrendous. I can just imagine chasing down compiler errors indirectly caused by an XML switch not set shudder.

JAXB looks like a bolt on to work around XML's deficiencies. There's no need to marshal JSON to special funky data structures in your code because lists and hashmaps are already built in. You can just use those. An equivalent doesn't need to exist.
For schema validation, I think XML has, what, 3 ways of doing it? DTDs? XMLSchema? And now JAXB does a bit of that on the side too? Does that sound like a healthy ecosystem to you? Because it sounds like absolute dogshit to me.
