That's how it used to be for your suggestion too. We're living in a dream state now where the creators of IDEs like Visual Studio (Code) or IntelliJ actively implement common languages and frameworks. It used to be 'find a half-baked community plugin so JSON works.' If someone made a standard schema and people used it, I can assure you the magic you are expecting from your tooling would suddenly pop in just like how JSON support appeared one day. But they can't do nothin' if there is no community support for it. XSD and XSLT are complicated because XML is complicated.
