> Traits? Nope. We need some way for code reuse.

Says who? You can totally do code reuse using manually-written dynamic dispatch in "rust without traits". That's how C does it, and it works just fine (in fact, it's often faster than Rust's monomorphic approach that results in a huge amount of code bloat that is often very unfriendly to the icache).

Granted, a lot of safety features depend on traits today (send/sync for instance) but traits is a much more powerful and complex feature than you need for all of this. It seems to me like it's absolutely possible to create a simpler language than Rust that retains its borrow checker and thread safety capabilities.

Now whether that'd be a better language is up to individual taste. I personally much prefer Rust's expressiveness. But not all of it is necessary if your goal is only "get the same memory and thread safety guarantees".
