Depends on your definition of "unexpected". OP was talking about reinstalls for example, where the root partition is deleted and recreated and its UUID will change as a result. If you copy an fstab from an older system backup you will fail the mount the root partition.

UUIDs can also cause some reverse trouble if you clone them with dd in which case they won't change but they should, and you end up with duplicate UUIDs.
