The problem with manefestos is they often harp on small parts that don't matter much in the big picture. There are real shortcoming of the C++ model, but if you use modern C++ they are rare.

The real shortcoming it is very common for people to not write modern C++. I know several C++ developers who refuse to use smart pointers because they don't like magic happening.

It's not enough for memory safety issues to be "rare". To meet your obligations under the standard and have defined behavior (i.e. rust's basic guarantee), memory safety issues can't exist at all.
