I've not seen or heard any evidence of any of the modules of the A330 MRTT MPS being certified for use, but it does appear to enhance SA very well.
The aircraft as a whole though, has achieved around 20,000 boom contacts and offloaded over 100M Lbs of fuel amongst its many operators.
I did hear that Airbus could start rolling A330 MRTTs off the production line after about 2 months of an order, ensuring they could "deliver the tanker well ahead of Boeing". Hard to say what 'Nonconforming' means without any output specifications being written for any specific orders or interim solution.
