> 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.

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.
