Isn't the reason we want/need this central accountability precisely the fact that everything software related is an extension of some web based software now a days? It's funny because we preach 'modularity' yet we keep building on this amorphous borg and then we get bitten by its complexity. Not to mention the enterprise drive to streamline everything and destroy silos.

Modularity requires redundancy, it's inefficiency that buys us resilience. But forcefully erasing emergent social boundaries on one side and forcing overtly complex structures for the sake of some ill define ideal on software architecture (OOP! microservices!) just nets us the worse of both worlds.
