Except that C++ provides the tools to do just like C, Rust, or whatever one feels like doing for dispatching, even if it requires a few pages of template metaprogramming mixed with compile time executions, or writing exactly the same C code on the common subset across both languages.

Now with reflection even more tools will be available.

Which is why despite all its warts and security flaws, many inherited from C source code compatibility, many domains will keep using it, because they will complain about their missing 1% that no one else uses.
