You'd likely get something like Flutter. It's actually gotten quite good these days with their web version, 300 ms to load a counter app, and 150 ms with WASM enabled.

There's a great post by Ian Hickson, the project lead of Flutter, about how we might have more WASM based web apps while keeping the DOM for content based websites:

> This document proposes to enable browsers to render web pages that are served not as HTML files, but as Wasm files, skipping the need for HTML, JS, and CSS parsing in the rendering of the page, by having the WebGPU, ARIA, and WebHID APIs exposed directly to Wasm.

I first heard of him via "Towards a Modern Web Stack (Ian 'Hixie' Hickson)" on HN [0]. Quite interesting. Note that the submission link is broken, the google doc link is added below [1].
