Svelte is pretty close to this (at the expense of a build step). It gives you (in my opinion) better ergonomics that React, has no runtime and outputs sites that don’t require JS unless they do.

Sveltekit (its official fullstack framework) even encourages building apps that fall back gracefully for users with JS disabled.

Of course, none of that is to say that you can’t build bloated, badly performing apps in Svelte. Just that you *can* have the best of both worlds, even for simple/static sites.
