I suspect that the momentum behind the project is having a group of core developers (Kling foremost) that have complete knowledge of all the moving parts. This allows a small team to make changes quickly while keeping the whole cohesive and without the slowdown of deliberative bureaucracy. Maybe it’s like the human organizational equivalent of L1 cache. It’s like riding a wave, a situation that can’t last forever. I have been part of teams that did the work of much larger teams. It’s great when that happens. The last mile might be less fun, but this entire OS is a labor of love.
