We can't follow all marketing trends (Apple recently renamed iOS to iPadOS for the iPad; we can't keep adapting to such schemes). Personally, I like the new name without the "x", but we had already spent some time trying to find and fix all (or at least, most) instances of "osx" in the code, that I don't really think it's worth the effort.

If they do something surprising, sure, but here it's more of a "it's needed on aarch64 to work at all", so I don't think a comment will be anything but added clutter.

@magicus - I'm good with both of these answers. I personally like 'macosx'.
