I appreciate that people use the new features in C++23, but I don't like that what's supposed to be a very basic system utility relies on compilers not available except in the newest of distributions. I mean, sure, you can also download and build a modern C++ compiler, but I would have swallowed my pride and written it using somewhat older C++. I maintain a GPU-related C++ library which assumes C++11 and no later - even if C++17 constexpr goodness would have made some of it easier to write.
