Missed the "better idea" which is using part of the rotating ID for something called "secret sharing" that lets you determine which IDs belong together after gathering a few random IDs. Eg, you have 3 IDs and they look unrelated and you get a 4th and boom the math works out and now you know you have a rando airtag in your pocket.
