There's a common theme in posts like this where the writer knows _too much_ about programming, and tries to do things that are awkward in Rust, but a lot of these problems don't actually come up in practice. Sometimes I feel like they take it as a personal challenge to never ever use .clone() and like -- it's okay -- use clone(), nobody else is going to know.

I'm maintaining 4 kubernetes operators written in Rust with a team of devs who are _not_ brilliant developers, and it's all async, and once I setup the patterns, they were able to jump in and start contributing business logic immediately.

Is it the most performant possible implementation? Definitely not! But once I told them how to stop using unwrap() everywhere, they have literally _never_ crashed or panic'd in over a year. When we were working in go, nil pointer exceptions were the bane of our existence.
