Is the mingw-w64 project slowly integrating WinRT?

[ghost]

I see the various new headers with the format windows.something.h in the include directory. The names are identical to the one provided by the cppwinrt package on MSYS2 (https://packages.msys2.org/packages/mingw-w64-ucrt-x86_64-cppwinrt), but it seems not all cppwinrt headers are included. I also see the wrl directory in include (WRL = Windows Runtime Library).
