Isn't the thing that makes UUIDs UUIDs that they have enough bits that they are guaranteed to be unique without any synchronization?

I don't think you could reduce the amount of random bits (I guess there are some non-random parts in standard UUIDs but not a significant amount) while preserving that property unless you add back some other form of synchronization to ensure that there aren't collisions which seems like it would defeat the purpose.
