I agree, there's no silver bullet, only tradeoffs and our appetites for them.

From looking at the list of crates above, I see a lot that are often part of the stdlib of other languages, such as HTTP, concurrency/nio primitives, and logging.

My perception of Rust's not including such fundamental primitives in the standard library is that Rust is still very much experimental, and the ecosystem values tinkering and experimenting with new ideas. The cost of that is increased dependency hell, especially over time. There's obviously huge value in experimentation for the industry, but it makes me hesitate to use Rust for projects where I just need to get stuff done, and stay done.

HTTP libraries are a prime example of where many, many standard libraries are considered old and crufty, and there are much better ecosystem libraries that end up being wildly used more.

You may have that perception, and that is fine, but it's not likely to be a thing that changes significantly, even when Rust is quite old. There's just not a lot of advantage to being in the standard library, and numerous downsides.

We should be more nuanced than that. There are also many standard libraries where the HTTP implementation is the standard. Why?

Look at those huge lists of dependencies and the complaints of Cargo dependency hell. That's the downside. Every node in your dependency graph has overhead for everyone involved, and it's even worse when it's something as fundamental as HTTP.

Yes, there are downsides to every approach here. That's just life.

I write a lot of Rust that never touches HTTP.

Isn't that exactly why you'd use a package like hyper that wraps the pieces together for you?

I'm less experienced with rust, but with nude, there's many times I'll use a specific dependency over another because it's already in the dependency tree.

Aside, it's rough actually trying to keep node dependencies in check in a project. Especially in web UI projects using npm.
