alt Hacker NewsI believe current official guidance if you want a lot of random data is to use v8, the "user-defined" UUID. The use of v4 is strictly less flexible here.

No, UUIDv8 offers 122 bits for vendor specific or experimental use cases. If you fill those bits randomly, you get the same amount of randomness as a v4. The spec is explicit that it does not replace v4 for random data use case.
> To be clear, UUIDv8 is not a replacement for UUIDv4 (Section 5.4) where all 122 extra bits are filled with random data.
