I don't think it's particularly exceptional for the sorts of people that are still using C++ (and making a conscious decision to do so over Rust for e.g.).
If you're writing 'standard' C++ these days, you're probably already making use of std::array, std::vector, etc. anyway. The only area where people are working on modern codebases I've not seen so much of that is in HPC stuff and embedded.
