Yeah, we're getting close. I'll reopen this issue for tracking.

We still need that pip release and it'll have to be merged into ensurepip. We'll also need better access to test systems than any of us currently have (the buildbot is great, but we need interactive systems too).

There are already binary releases at https://www.nuget.org/packages/pythonarm64/ that should be suitable for most testing. I'll probably make the ARM64 packages available through the Windows Store for 3.11's prereleases, and possibly as a side-loadable MSIX from python.org.

I'm strongly considering not offering the regular executable installer on ARM64, since it seems we don't have the back-compat demand right now. It would be a good opportunity to try and fix the issues with that installer and really put the focus on the MSIX as the user-friendly approach. But that's still future thoughts, no concrete plans yet :)
