re: #12 Charles

It’s a record of the cell towers your phone connected to.

Obviously, Apple needs to explain what this file is for (and it should be encrypted, also obviously), but I predict it’s going to end up being completely unrelated to “tracking” anybody.

It’s worth asking Apple what they lose if this data is not kept any longer than what is necessary for functionality. I see no need for a record of yesterdays cell towers to function well today. I suspect they can do without this record existing at all.
