>"Managed languages make such refactors trivial, while C++ and Rust (even with its very advanced type system) make these harder due to you having to rearchitect the whole program from a memory model perspective. Sure, it can be trivial in many cases, but not always."

This is not the function of the language but the ability of the developer to properly architect their code.

And tools like Visual C++ / CLion have very advanced refactoring features.
