While I'm writing all this essentially criticising Mark, I can't help but think how it's a part of the character. We love him because he's who he is, with all his decisions, good or bad. His life is an amazing story of recognising your talent, overcoming difficulties, overcoming fame, and turning dire straits into Dire Straits. He's a human and humans make mistakes, it's what we all are very good at. All this "keeping the formula" stuff, keeping the musicians, doing everything with the same sound and same approach might not be the best way to do it, but it's Mark Knopfler's way.
