FFI is painful, to be sure. Making sure the bindings you say you're using match the ones you're actually using is tedious and error-prone. Which is where CXX comes in: the static analysis tells you if you're holding it wrong. So to your first point, the compiler will tell you exactly what needs to change. I don't know what the developer experience with D/C++ interop looks like, but unless I'm missing something big I'd assume you'd still need to make changes when the library has updates.
