I was just exploring after talking to Diego. I think this is unfortunately not a big win because it can only run x86-64 wheels transparently and not arm64 wheels, the arm64 wheels would need to be compiled as arm64ec too which defeats some of the compatibility benefits. |

arm64ec-pc-windows-msvcdistributions for Windows 11 on ARM. CPython and its bundled extensions compile as ARM64EC while retaining an x64-compatible extension ABI and thewin_amd64wheel platform tag. The stable-ABI forwarding DLLs and the bundled OpenSSL, libffi, and Tcl/Tk libraries are built for x64.Adapt CPython's project configurations and atomic operations for ARM64EC, and include the target in the Windows build matrix and releases.
