I’m sure Rust started out as something intended to help with their browser work. But it became a general purpose programming language pretty early, right? I think it is… working pretty hard to find a reason to not include Rust as a innovative, non-browser piece of tech.

Anyway, I don’t really think it detracts from your broader point to count Rust as a separate thing from the browser.
