I believe in the code dictator model also. However, the code dictator takes a lot of heat over style opinions. What I see is that, when the dictator emerges, he still has to build coalitions out of people with different skills and different backgrounds. If there's a pool of mediocre or average developers, that is very hard to work around. Only the new people being added can really come pre-loaded with the right code-culture attributes. With non-new people, everyone has to be convinced about the code dictator's approach. This is just not a frictionless process.
