I don't get it either. If UUIDv7 lacks security due to its revelation of a timestamp, why don't bigserials also lack security? After all, given a bigserial ID, you can tell whether it was generated before or after some other bigserial ID and thereby infer something about the time it was generated. |

The use of UUIDs for documents may come from a no-sql background.
I use bigserials for relational data in relational databases, and if there is a unique document value needed, a UUID is good.
