With the overall KC-X, KC-Y and KC-Z legacy tanker replacement programs - of which KC-46A is KC-X - in a shambles - US TRANSCOM and USAF have now agreed to push ahead with part contractorization of the overall USAF AAR task - such as routine AAR training, trials, exercise support, Foreign Military Sales delivery flights etc.
I don't think there will be much chance of the KC-46A being the choice for KC-Y as well now.
A 2nd Industry Day for discussions of the art of the possible regarding contractorization was held on December 17, 2019 which was attended by 14 companies. Solicitation of bids is now expected June 2020.
It will be ironic if Airbus gets the contract with new-build / reworked surplus civil A330-MRTT which the USAF could have started getting 12 years ago if the original contest winner (KC-45A) in 2007 hadn't been derailed by vested interest interference which led to a re-run of the contest with parameters skewed towards Boeing !
