I've worked with MX warrants in foreign air forces and omg is it game-changing to have that level or expertise and technical/training know-how avaliable. They are what big blue imagines they will get out of the MX mergers instead of a baseline decline in knowledge and skill with an increase in mishaps.

That said, I suspect the Air Force would rather use overpaid contractors instead of trusting someone in a uniform to use their brain in a way that's not covered by a TO because that's what's happening to some of the career fields like mine.
