It is nice to see workarounds. But those workarounds are not conducive to HTML purists who do things without JS. They are the real web developers. They have always relied on the browser to improve and become faster but not start abandoning old technologies.
Chrome OS also became popular on this point that a browser can do things like being universal viewers and so the need for programs goes away. There are so many lite OS who are also using the browser to do everything.
Now I understand that the web has failed XML and XML failed the web in favor of JSON. I also whole heartedly believe that XML and XSLT can do so much more for the web and do this natively.
But open systems are not in the interest of the big FAANG and Microsoft ecosystem. They abandoned RSS. They abandon APIs on a regular basis. And this turn of events is causing browser vendors to start developing for big companies rather than open indie developers.
There is much gain from XML and XSLT. But I want to see a specific development. I want to see XSL import an XML. I want to see the reverse. XSL will be the view. XML will be the model. And the browser will be the controller. MVC paradigm.
