I think this is still possible.

It took a decade for JQuery to be nearly completely absorbed by browser standards.

For the most part, jQuery was absorbed into ES/JavaScript, not HTML.

The most visible part of jQuery for me was always querying selectors - $('.some > a.selector'); and that certainly was something integrated into HTML/the DOM as document.querySelectorAll('.some > a.selector').

Well yeah, that's still under "browser standards."

The difference is that the internet can exist (and did) quite well without JavaScript. Without HTML there is no internet. Furthermore, ECMAScript is a language and W3C/WHATWG are a consortium that maintain HTML.

Sorry to nitpick, but there is a lot more to the internet than the web.

And the browser APIs still have significantly worse ergonomics than jQuery
