I was using my new Magic Keyboard for iPad when I noticed something. It is a small thing but again highlights Apple’s delightful attention to detail. Watch the cursor change shade as I move it to dark/light areas of the screen. Important? No. Delightful attention to small things? Yes.
I actually do think it is important; the way they implemented it gives none better/best contrast to continue following the cursor. And yes, lots of other companies/developers would not have given much thought.
