Well, given those bullet points, Servo might meet your needs :)

In general we're not going to think about blessing packages as "official" unless it gets to the point where some package becomes mature and overwhelmingly dominant in its space (think Rack in Ruby or async in Node); we'd prefer to focus on making it easy to upload and share Rust packages via Cargo to build up an ecosystem.
