Yeah okay, but that's not the reason why people write it in the title. They write it in the title because they know that many engineers like Rust and think people will immedietly be drawn to it.

But the language itself is not a goal or at least shouldn't be IMO. Thus it have the opposite effect on me, who do not care about what language my bundler is written in.

If I did, it still wouldn't have any competitive advantage since as you point out Vite will soon also be based on Rust.
