I don't think this is relevant on three grounds:
1. Whether or not it was "made for" webdev, people do use Rust for that.
2. Plenty of people write networked Rust that interacts with HTTP. That code requires an HTTP stack, even if it isn't web development.
3. Like all of the other examples, Rust does have an excellent third-party HTTP stack (reqwest and its underpinnings). So it's not like Rust fails to do HTTP.
