My project currently has 104366 lines of Rust code and 174 uses of 'unsafe' (many of which are somewhat spurious, like usage of `mmap` and other system calls that don't have safe wrappers in external crates). My project does a lot of low-level stuff (e.g. ptracing, sharing memory with C++ code in other processes) and has lots of crazy low-level optimizations but still only has one use of 'unsafe' per 600 lines of code. I haven't made any particular effort to reduce usage of 'unsafe' either.

Sure, but using 'unsafe' everywhere that you would write unsafe C++ code simply isn't idiomatic Rust and except for very specific and limited situations, Rust developers don't do that.
