I didn't say Rust is doing the right thing. And it may create other issues where it does not 100% correctly reveal the issue.

However, I'd still say that issues arising in sharing a composite structure in pieces have always existed. Rust's solution may or may not be correct, but the issue is not something it is creating. Adopting Rust does not mean adopting a brand new set of problems that never existed before. It means seeing them clearly for what is probably the first time.
