Now I've tried that test, on macOS, it presents something radically different to my normal use of the mouse.Actually, I think that there might be drivers for opening at least some of those filesystems in Windows (even if read-only).
The thing of it is that it is lesser performing and horrible to use, comparatively speaking. And not just by a small amount. A 20-40% drop in performance is significant. As you put it, "it works," but does so badly because the method by which it accelerates is utter trash. It has precisely nothing to do with gaming. In fact, it's for basic productivity and desktop tasks where this flaw is most obvious and critical.
As for the ignorance-is-bliss argument, I suppose that's valid, but now that you know the problem is there and can see the difference for yourself, (again, test on classic.mouseaccuracy.com in both environments if you don't believe me) it can't be un-seen. Especially if your day job requires precise mouse use for hours on end like mine. If you're just leisurely goofing around on the web here and there, not doing anything mission-critical or time-sensitive, then I suppose it matters less, but even then, you should still have higher standards for technology. This was figured out decades ago, so it's not too much to ask of a modern operating system.
For example, I might be reading some text and realise there is a mistake. So I move the mouse pointer to the location of the problem and am thinking about the issue. Ready to select and overtype or whatever. Indeed, I often give my mouse no conscious thought - and it is often exactly where it needs to be.
And a lot of the time I know where things are - they don't just appear randomly.
