Sorry I'm a bit confused. I'm in agreement that a natural key shouldn't be used as the primary key for a record. I was responding to a comment about having a hidden "database ID" (which I interpreted as being a serial key?) and a public "Uuid", and questioning the utility of that hidden database ID versus having a public UUIDv7 as the sole primary key, followed by questioning whether the utility of obscuring that primary UUIDv7 is worth the complexity of having to manage multiple artificial keys. I agree that security through obscurity is a valuable layer in a multi-layered security position. I guess I just don't think obscuring a Uuid primary key is worth the added complexity in most systems. I see it like adding a second front door to your house with a separate set of keys. Sure it'd be more secure, but it's an added pain and doesn't help if you don't have a sturdy doorframe, or smash-resistant windows.
