> a big "unsafe" dunce cap to shame you for being a naughty, lazy programmer

That's bizarrely emotional. It's a language feature that allows you to do things the compiler would normally forbid you from doing. It's there because it's sometimes necessary or expedient to do those things.

My point is that using C FFI is "the things the compiler would normally forbid you from doing" so if that's a major portion of your program then you're better off picking a different language. I don't dislike rust, but it's not the right tool for any project that relies heavily on C libraries.
