I think just attributing this to the right people not being in charge over simplifies the problem. Search is a complexity beast and simply continued to grow in complexity during the several years I worked directly on it. Folks were proud of the fact no one could even enumerate all the features in the system (attempts were made and abandoned). The tools to change search safely werent keeping up with the complexity of the system. Understanding impact with evals and experiments became much harder. Gwsdiff and friends grew flakier. Debugging had so many different entry points depending on what you needed to do. The search stack deserves some really deep cleanups and refactoring, the eval and devtools are similarly in need of a ton of love.
