That's a great point; I should definitely have included it in the list! I think new projects (especially ones that seek to innovate) have two phases: in the first phase, everyone's trying to kill it; in the second phase, everyone's trying to grow it. The kill-it phase is actually valuable for exactly the reason you outlined: it gives a small team the chance to create something highly coherent. (The grow-it phase is sometimes worse than the kill-it phase, but that's an entirely different story).
