And it’s likely not compatible with a C++ compiler.

  It definitely isn't. C99 and even some C11 features used all over the place. Designated initializers are heavily used. We'll see when those actually end up stable for C++20. Even then, I never use the latest standards of C++, I stay a couple standards behind so I can rely on whatever compiler I pick being able to handle it. Right now I'm using C++14.
