I think they were just afraid of the birthday paradox. But I agree, just grabbing some random bytes really is the way to go.

Although, I'm a bit afraid of the birthday paradox, maybe we should use 20 bytes instead....

The idea that a UUID should have a "version" and the random one uses 122 bits instead of 128 bits sorta makes ya wonder how concerned they were.
