The react world has flow that does the same type checking, for the bundling webpack is now superior, and warning is handled by eslint, and with babel for ES6, and PostCSS for css next I don't think there is a lot of reasons to use the closure tools apart for the components.

The fact that your list is that long is a good reason. Using best-of-class libraries is brilliant (and I'd like to all the time), but using good-enough libraries that are well tested with each other and unlikely with new releases to change behaviour in ways that will create edge-cases or interop problems: that is pragmatic.
Plus the reduction in developer-rabbit-holes when every developer tries to include its own favourite (Webpack! Browserify!), the consistent documentation, and the ease of setup.
Not to say you're wrong, but I feel people overlook the benefit brought by well-developed monolithic frameworks.
