UUIDv7s are much worse for creation time though imo. For sequential IDs an attacker needs to be have a lot of data to narrow the creation time. That raises the barrier of entry considerably to the point that only a committed attacker could infer the time.

With UUIDv7 the creation time is always leaked without any sampling. A casual attacker could quite easily lookup the time and become motivated in probing and linking the account further

When sequential integer ID's are externalized, an attacker does not need creation times to perform predictive attacks. All they need to do is apply deltas to known identifiers.
