I find it difficult to articulate, so forgive me if I'm not getting my point across, but the gist of what I'm trying to say in that section is less about straight binary compatibility and more about API design in general, playing to the respective language's strengths. I feel like Rust encourages more "C-like" APIs, and its added features (such as memory safety) are in effect the whole running time of the program, regardless of where that memory comes from or how it's initialized. On the other hand, C++ has something of a vendor lock-in regarding how it functions - RAII, constructors, exceptions, inheritance, etc. etc. all assume you have objects with a lifecycle that starts and ends in C++, and that those objects see most of their use according to C++'s object model. All of C++'s features come together in a brilliantly harmonized way and build off each other, but, if you forgo even some of those features, you end up missing out on most of them.
