There was previous discussion in #8148 regarding a Windows on ARM wheel. That was closed with these comments:

We won't ship a wheel for a platform we can't test in CI and GitHub does not currently offer arm64 windows runners. When they do we'll revisit this though! (see: pyca/pynacl#775 for some past discussion in another repo we own)

and

In the absence of some indication from gh that this is even on their roadmap, this is pretty inacationable for us, so I'm going toclose.

GitHub have announced arm runners: https://github.blog/2024-06-03-arm64-on-github-actions-powering-faster-more-efficient-build-systems/ and as an owner of one of the new Snapdragon X ARM laptops I'm keen to simplify installation on this system.
