Some software bloat is OK

If I could make one law related to software, it would be to ban React and React-like frameworks (includes Vue and Svelte I believe): if you have to put more than one line of HTML in your JavaScript, if you have VDOM, if you have a build step - I want this to be illegal. It is entirely possible to write a js-framework that attaches itself to DOM from the top, without any kind of expensive hydration steps or VDOM or templating (I've built one). React is a horrible complex monster that wastes developers time, heats up users' CPUs and generally feels super slow and laggy. 99% percent of websites would work a lot better with SSR and a few lines of JavaScript here and there and there is zero reason to bring anything like React to the table. React is the most tasteless thing ever invented in software.

Why not ditch HTML itself? People are already downloading binary blobs on a daily basis anyway, just download some binary once, execute them in some isolated environment. So you only have to transmit data.

Do not know to what extent you are serious, but I think the idea is that content should be HTML and apps should be just JS.

We could go further and have a language written to run in a sandbox VM especially for that with a GUI library designed for the task instead of being derived from a document format.

Yeah, I think my point was misunderstood: part of what I'm opposed to was writing HTML (or worse, CSS) inside .js files.
