I don't understand why JSX is still being used. Why should I a HTML developer change how I write HTML for a framework? And why doesn't it allow style tags?
Svelte lets me use HTML, style tags even a script tag. The only framework that is close to HTML is Svelte. The second version even had .html extension which is now .svelte.

You can 100% use style tags in React, they just aren’t automatically wrapped in module/component scope. Just like normal HTML style tags, actually.
As for JSX, I personally have always hated HTML template languages (“now which slightly-different version of the for iterator does this template get use?”) but I also recognize that there are other people who have opposite preferences. JSX-in-JS and template-directives-in-HTML are both valid approaches and it’s great that there are solutions to cater to various preferences. Trying to argue one down because you don’t like it is like arguing that your favorite color is factually superior.
