Rust has improved a lot in a lot of areas, and most of that has been lead by external people! Think of the work in WASM, or in async IO, or even in webframeworks (like rocket). All of this was independent work, and it's some of the best improvements made for Rust.
Rust isn't great at web servers yet, but that takes time. An official team could accomplish this, but there would need to be significant benefit. People are already innovating, finding new solutions, and improving code. Projects like tokio, async-std, actix, rocket, tower, gotham are all improving the state of writing web servers in rust without any official team. We can, and will, improve the state of Rust ourselves, as other areas have been improved (like server side tooling, like writing OpenGL apps, like writing client-side WASM).
No any body care about rust, especially the rust team.
I find this especially untrue. The rust team does a lot, it's just that most of that work goes into rustc itself. They write the foundation which everyone else builds on top of!
And to say no body cares would be to ignore the entire crates.io ecosystem. It's a very different model than languages like Java follow, but independent people making and improving crates make Rust what it is today. The myriad of production uses of Rust exist because of the thriving ecosystem of crates. The Rust team plays an important role - building rustc (and cargo, crates.io, etc.) - and the system works.
I definitely recommend looking at projects like rocket and gotham, or the summary page arewewebyet to look at progress. We don't have the same m as other languages, but we're consistently moving forward. It's ten times easier to create a web app today than it was a year ago - and that's not even counting how much nicer async/await is for asynchronous programming than other stuff!
It's just that Rust has had 4 years, and Java has had 23. Or if comparing to a language like Go, Rust is a much more general language, and it's main goal is not to just write nice web servers.
