I suppose usually one would like to have everything from a language standard.
The C++20 winning run seems to have been one of a kind, and whatever made it possible is now gone.
Speaking of gone, Herb Sutter has left Microsoft and most certainly had to do something with whatever is going on MSVC, C# improvements for low level coding, and Rust adoption.
