The "we have to" is because all the game development middleware is written in C++ (and sometimes C), the same way you "have to" use Javascript for writing web applications (even though WASM is beginning to change that, but it took 25 years to get there).
Actually, only half of the universe is using C++ to write games, the other half is using Unity and writes their game code in C#.
If language interopability would be dramatically better, this "lock-in" into a specific programming language wouldn't be half as bad as it currently is, and it would be much easier and less risky to use "fringe languages" for game development.
