It's not just about GC pauses. Rust isn't "little Go" that you reach for only when you can't afford a GC. Many people choose Rust for the cargo package manager, generics, pattern matching, mature optimizer that prioritizes runtime speed over compilation speed, ability to write libraries callable by any language, fast FFI, compiler-enforced data race prevention, memory safety in multithreaded mode, etc. etc. These benefits apply to servers too. And many of these benefits are what lead to the futures model being more appropriate than the M:N model for the language. Go has its benefits too, of course! One of those benefits is that blocking I/O is a simpler mental model. Both languages can happily coexist without one being in the shadow of the other.
