Do you grok what the issue was with the unwrap, though...?

Idiomatic Rust code does not use that. The fact that it's allowed in a codebase says more about the engineering practices of that particular project/module/whatever. Whoever put the `unwrap` call there had to contend with the notion that it could panic and they still chose to do it.

It's a programmer error, but Rust at least forces you to recognize "okay, I'm going to be an idiot here". There is real value in that.
