I think there is a strong culture in the Rust community to use `unsafe` carefully, somehow fostered by the overt advertisement, features, and/or design philosophy of Rust. The infamous actix-web debacle suggests that Rust users tend to be overzealous about avoiding `unsafe`, even. I think the design philosophy plays a big part to develop the culture: `unsafe` is less seen as the thing that only super hacker wizards use, and more as a tool that should be used judiciously but still out in the open.
So I suppose it's not literally just the Rust language itself, but given the context of Rust's development, there seems to be an intertwined culture that was more likely to arise than not.
