Go had this issue for a while, too, it's finally started to calm down as Go hits a mainstream that is (imo) much farther than Rust is currently. I think much is just people trying to add validity to Rust for large-scale production workloads, in the same way that Kubernetes was "a compute scheduler written in Go" or Terraform was "infrastructure as code written in Go" (maybe those are bad examples, but I know I've seen the "X written in Go" thing going on).
