I agree technically but in most use cases the timestamp from uuidv7 is not a security leak. Especially where you’re already sharing that data in some way or another. A default guid is unnecessary if you use uuidv7 I think (in most situations).

It's more for performance that you shouldn't use them as PK's - If you insert a lot you'll get massive fragmentation over time. A sequential Id avoids that and still gives you a unique row.

The Guid is purely for an external system to grab onto something that I can tie back to an actual row in the database but the external system does not need to know anything about the backend other than <guid>.
