Safety is almost never functional requirement (unless for OpenSSL and such projects). You can always focus just on the happy path expecting users will behave. Even in Rust you can unwrap on unexpected value instead of handling it properly. It will lower the LoC, thus increasing readability but possibly crashing the program on unexpected inputs. Possibly leaving open doors for DoS where attacker would just spam invalid input and crashing the server.
