I think it's the latter. most people don't care about decentralization. Staging is more of a nuisance, there're some projects which try to eradicate it (https://github.com/martinvonz/jj). But I think git won the last decade because it is conceptually simple and elegant. You can reason about it in the case of any trouble. You can reimplement it if needed and be absolutely sure that reimplementation is fully compatible, because it is THAT simple.
