There's nothing about UUIDs that need to make them cryptographically secure. Many programming language libraries don't (and some explicitly recommend against using them if you need cryptographically strong randomness).

Not for security but to make sure you don't accidentally reuse the same seed. I've done that before when the PRNG seed was the time the application started and it turns out you can run multiple instances at the same time.
