I feel like D has gone this route of incrementally adding features (like borrow checking) to the language that, in principle, improve safety. I wonder if anyone here has more experience to know how well it has worked? One massive advantage of Rust is that they started with borrow checking from the beginning. I think one thing that often gets understated in these discussions is how much it matters to have your entire ecosystem using a set of safe abstractions. This is a major drag for C++, and I suspect that even if the language went a route like D they'd still have gaping safety holes in practical, everyday usage.
