I have single datasets with trillions of UUID. Collision probability becomes a thing.
That aside, UUIDv4 is banned in many orgs because there have been several instances in the wild where the “random” number wasn’t nearly as random as advertised from some sources for a variety of reasons, leading to collisions. It is relatively easy to screw this up so many orgs don’t risk it.
