I think one should not underestimate the powers of the not-so-good-team to make anything go sour. Who says the not-so-good-team isn't going to make sure that any change needs to touch at least 3 repos and quite regularly as many as 10?

As for the philosophical issue that yosefk raises, I generally advocate solutions that work for the case that the team is good. I tend to think that if the team is not good you would be cooked anyway. Also, if you raise the stakes people might actually start learning a bit.
