No, as much work means that you can't use 99% of C++ in C FFI. You have to fully instantiate template functions, template structs (you can pass `std::vector` to C FFI), etc. before you can expose them to C.

If you are writing C++ in such a way that this does not matter, then you are basically writing C already and `extern C` is all you have to do though, but then you might as well just have been using C this whole time.

having done this process for multiple libraries using a lot of fancy C++ >=14 features, I really think that it's not a big deal - at most an afternoon of repetitive work if you have an API with ~100 functions.
