I think my claims are that it forces ODR violations across C++ versions itself given the existence of Clang's extension. In pure C++ code, `_Atomic(T)` is a builtin type (the Clang extension) in C++17, but it can be `std::atomic<T>` (a standard library type) in C++23. I agree that ODR violations between C and C++ are more philosophical.
