If Rust occupied the same market niche (better and easier than C++ for large companies!) as Java did in the early 2000s when such features were considered desirable by paying customers, it totally would have been implemented. Rust is able to learn from the many mistakes that other languages before it have made. But pretending that this means Rust is inherently purer instead of just "has less baggage, but will soon implement its own", is naive.
