I work in a 400k+ LOC codebase in Rust for my day job. Besides compile times being suboptimal, Rust makes working in a large codebase a breeze with good tooling and strong typechecking.

I almost never even think about the borrow checker. If you have a long-lived shared reference you just Arc it. If it's a circular ownership structure like a graph you use a SlotMap. It by no means is any harder for this codebase than for small ones.
