FWIW, I'm aware of a handful of people that work for a very large AAA game studio, nearby where I live, who are, in fact, git "experts" -- and, really, just extremely knowledgeable about version control systems, generally speaking, since they don't just use git -- for the company and they spend a large % of their time helping these teams deal with version control issues. As I understand it, they've written a lot of automation to deal with recurring problems like merge conflicts, perforce depot / workspace issues, etc. And they make good money for that expertise...
