I can agree that CSS is really unpredictable. However ,not being able to put CSS in a file isn't a small change. It makes other people to read the code harder, and mixing css and js just doesn't feel right. But just to keep my self safe, I know how people reacted to react at first. This might be normal in the future. Maybe.

Exactly. And we won't find out if we don't try. Also, specifically, this approach is more JSON-based (compared to other CSS-in-JS). So you can easily put styles into a separate file if you want, JS or JSON. But I prefer defining styled components in a separate file, as `styled-components` recommends.
