In a sense it still does - uncontained engine failures are considered to be a 10-7 to 10-8 event. Current airframer guidance for uncontained engine failures is to do what is known as a "one in twenty" analysis - basically showing that the probability that an uncontained failure will do catastrophic aircraft damage is no greater than 1 in 20 or 5%. So that takes an uncontained failure causing catastrophic airframe damage into the 10-9 range.
