Not to nitpick here, but Google's cloud libraries and Amazon's AWS libraries work because there're probably a dedicated team of engineers who're assigned to these projects, considering cloud platforms are supposed to make these giant orgs a ton of money. When Google needs something, it gets built, corrected and optimized quickly (e.g. Go context library). Open source / crowd sourcing doesn't work that way.
