You don't need it, but plenty of devs prefer it. Our shop switched from Python to Rust. We almost went Go, but in general the language didn't feel like it was solving enough problems over Python.
Rust gives us a nice type system and performance, in an enjoyable package.
We certainly don't need it (well, maybe in a single service), but it's our choice. The decision was largely Go vs Rust, but again, Go just didn't offer enough to us.
I agree though, a GC doesn't prevent us. Ours was a language choice, not a performance/GC choice.
Catching a bunch of bugs at compile time without having to write tests for them is real nice

As a programmer battling a C++ dependency, being able to write tests without having to bring in a 3rd-party testing framework is real nice too.
I'd guesstimate 99.9% of web developers have no experience with native non-GC development. Asking them to embrace non-GC is a big ask when GC is not a performance bottleneck for common cases.
Save Rust for serious apps by elite teams. You don't need Rust for average Joe web services that do little more than ferry data around.
