I think you are too late: the draft for the relevant part of Ada2012 is at http://www.ada-auth.org/standards/12rm/html/RM-G-3.html. I believe that the gate closed in November '09. The issues on Ada2005 are at http://www.ada-auth.org/AI05-SUMMARY.HTML, none of them ask for extended matrix operations, so no wonder there's no change. I know this is a chicken-and-egg thing.
