Google reports 4x fewer (and still falling) rollbacks for Rust versus C++ in their Android development for example. That's not 10x but it's pretty sizeable.
Naturally there are several ideological questions between that approach from the anti GC crowd, and adopting Rust instead.
Not that breaks the C++ vs Rust from your comment, though.
Folks that wonder pre-history tech with amazement and lack of understanding of how it used to work in first place.
The Red Black tree, C++ std::map is a classic example. It has these very attractive theoretical properties, but then you try one for real in C++ and oh, why is this so slow and so RAM hungry? Well yeah, those are only real world problems, the big-O numbers don't care about that.
Ironically there are C# implementations that perform better, exactly because they were developed without WG21 working environment, in a compiled managed language.
For all the performance minded talk, the walk doesn't always follow.
Also std::map cannot be improved by existing processes.
It doesn't take much for one memory inefficient dep to drag down the entire app.
