Two years ago I would have invested some effort to read this thoroughly and try to stay on top of the API changes. I'm sure it's helpful to a lot of folks.

For sure I do care about my build toolchain. The nice thing about being a React developer today, is that thanks to create-react-app, more specifically react-scripts [1], I'm thankful I get to choose to not worry about it. Just like I didn't have to worry about 2.0 -> 3.0 last time.

Cheers to the CRA maintainers. Thanks for giving me some time back!
