I'm not sure why this is a problem. In its purest sense, an ID is simply an ID - a means of identifying a "record" of something. If the customer is relying on the ID for information other than its intended purpose, then they're setting themselves up for failure. The customer needs to be educated and, perhaps, the product needs to be updated to expose more meaningful information (note: I've not actually looked through the product to see if that information isn't actually already exposed).
