The more recent ones make use of Objective-C runtime API called 
directly from C++,

https://developer.apple.com/metal/sample-code/

Objective-C++ documentation is gone from 
https://developer.apple.com

HPC cares about MPI, OpenACC, SYCL and CUDA, they will go with 
whatever version they support.

Also they are already good served with HPX (C++11 based).

MSVC only matters for Windows and XBox developers, and the new 
push is most likely triggered from WinDev and XBox business units 
not being .NET fans, contrary to what is happening at Azure, 
where .NET, Go, Java and Rust rule the party.

So that leaves GCC, and how much Red-Hat/IBM care to keep it up 
to date post ISO C++20.
