Wait, maybe I'm confused, but isn't the point behind rotating serial numbers that the person couldn't just click ignore? But how much sense does that make, if people are routinely ignoring tracking devices glued to their cars instead of finding and disabling them, that seems like... a problem. A tracking device that decides to re-alert you to its presence rather than remain hidden and silent seems like a less dangerous tracking device, rather than the other way around.
You can either rotate it after the time period where it alerts them, to be annoying (they have to keep dismissing it). Or, you rotate it before it alerts them, and stitch the tracking together. That's the more dangerous bit. Apple only alerts if a specific tag is following you for more than X whatever.
