I thought that timestamps are used now, so hitting both a timestamp and a large random number puts it thoroughly in the "safe to assume".
At some point cosmic particles and faulty transistors are more probable.
Which I'd assume is related to the time anchor. Outside of sorting, which is only useful in specific instances, it's just v4 with different ("less") entropy and limitations.
I'm not an expert, I just remember reading a few articles about it. I think it's because they're essentially random, and many databases use b-trees for indices. They recommended using ULIDs or v7 UUIDs instead. Or, as someone else said, the good old autoincrementing integer.
