The cost is nominal. They have many more of these as they were surprised to find that they last much longer than expected. They were spending 50 million per flight on these. Now they effectively pay 2 million. It's flown 19 times so has already saved about 900 million in costs. And realistically.wqs going to get sunset at some point anyway. Its dirty cheap to replace relatively.
