> What I am saying is that an evolution of the C++ model is much more ergonomic and less viral than this ton of annotations with a steep learning curve where you spend a good deal of your time fighting the borrow checker. So my question is:

That "evolution of the C++ model" (the C++ Core Guidelines) has an even steeper learning curve than Rust itself, and even more invasive annotations if you want to apply it across the board. There is no silver bullet, and Rust definitely has the more principled approach to these issues.
