I never run into this myself in modern C++ and I think it is about what I don't do. This might be similar on some level to the fact that rust constrains programmers purposely. I think both cases are indicative of better programming through avoiding things that are hard to get right and have little to no upside. I almost never use shared_ptr, since I know the lifetimes of the memory I use. I know the lifetimes because I keep almost all actual memory management within data structures made of mostly STL data structures. The custom data structures don't need destructors because vector<> will take care of it etc. I never use inheritance and never use polymorphism. The core logic then just uses these compound data structures made from STL containers and the lifetimes are frequently trivial.
