Imagine thinking that Scott fucking Hanselman isn't qualified to work on Windows. Jesus dude.
Mark Russinovich would be a different story, but he seems to be mostly concerned with Azure nowadays.
Scott is well connected in the dev and azure divisions. He has headlined dev conferences etc. But as an evangelist he only carries information. This change will not happen because of him but maybe with him. But I do not believe so. To much money at risk.
Even though it's been said many times that MS doesn't give a fuck about personal users, their money comes almost 100% from companies using Windows. Gaming computers etc. are a rounding error.
