That's what I don't quite get. I'm really wary of a "from scratch" web browser at this point. I looked at their project and their main selling point is that they're building both the rendering engine and the JS runtime from scratch "Driven by a web standards first approach" - what exactly does that mean? Firefox has always had that approach and web standards are more complex than they've ever been. I don't understand why not using code from other browsers is supposed to be a selling point when all the major browsers have open source rendering engines and runtimes and there's independent runtimes being built like Bun that they could use.
We're talking decades of features they have to support - unless they're planning on strategically dropping support for older unused/deprecated parts of the standard? Even in 2008 Google made the decision to use Webkit for their browser because they understood what an enormous undertaking it would be to write their own rendering engine. That was 16 years ago.

Th selling point is to have multiple implementations of browser engines. Currently we have three (gecko, webkit and blink, where blink is based on webkit and webkit is based on khtml). If you consider how much of the modern world is based on browsing standards it seems pretty self-evident to not have it depend on a few corporations.
Bun is a wrapper around JavaScriptCore (the JS engine used for webkit just like v8 is used for blink or node), so not at all an independent JS runtime and is not at all a browser.

If this is proven not to work because the standard has grow too big as you imply then we should absolutely look into either dropping old standards or slowing the pace we introduce new standards. This project is a litmus test for the web.
