Lol, that "worst Cloudflare outage since 2019" a couple of days ago was because somebody put an .unwrap() into a Rust codebase? I have so many questions...
...tbf though, "let it crash" isn't bad for a backend-service, but the other half is that you better make damn sure that each crash-path is properly tested, especially that the service properly recovers - maybe they should have used Erlang instead ;)
