And because it's real CSS, rather than some camelCased quotes-everywhere impostor, we can take advantage of the 'tweak in devtools, paste back into our source code' workflow, which I personally couldn't live without.

Many changes, including bug fixes and documentation improvements can be implemented and reviewed via the normal GitHub pull request workflow. Some changes though are "substantial", and we ask that these be put through a bit of a design process and produce a consensus among the Yarn core team. The "RFC" (request for comments) process is intended to provide a consistent and controlled path for new features to enter the project.

However, it did require us to think differently about the creation, maintenance, and sustainment of our components moving forward — an integrative process we call "storybook-driven development."
