Given how long and widely C++ has been a dominant language, I don't think anyone can reasonably expect to get rid of all the unsafe code, regardless of approach. There is a lot of it.
However, changing the proposition from "get good at Rust and rewrite these projects from scratch" to "adopt some incremental changes using the existing tooling and skills you already have" would lower the barrier to entry considerably. I think this more practical approach would be likely to reach far more projects.
There's been plenty of interop options between C++ and just about anything for decades. If languages like D, that made it piss easy, weren't gonna change people's minds, nothing can. Ditching C++ is the only way forward.
Interop between Rust and C++ is pretty bad actually - I can understand wanting to avoid that.
However I still agree. I can't see opt-in mechanisms like this moving the needle.
