UUIDv7 has a 48 bit timestamp, 12 bits that either provide sub-millisecond precision or are random (in pg they provide precision) and another 62 bits that are chosen at random.

The A UUIDv7 leaks to the outside when it was created, but guessing the next timestamp value is still completely unfeasible. 62 bits is plenty of security if each attempt requires an API request

... and the next person working on the system thinks "well, this thing is unpredictable, so it's OK if I leak an unsalted hash of it". If they think at all, which is far from certain.

Why does everybody want to find excuses to leave footguns around?
