Does that mean arm64 binaries are going to be even more portable?

That's right - the new build process allows us to more easily target older distros in our builds.

To clarify, from 7.0.4 we changed the minimum libc for arm64 from 2.27 to 2.23. .NET 8 will match that (and also target 2.23 for arm32).

- Alpine: [musl][musl] 1.2.2 (from Alpine 3.13)
