Huh, my opinion is that it’s potentially the right fit more middle-sized projects, but neither big nor small ones.

For small projects, you’re wasting time with a massive abstraction layer when you could be writing a small set of easy styles in plain CSS. You don’t need the weight and complexity of a sizeable framework.

And for big projects, it’s technical lock-in and additional maintenance overhead that absolutely doesn’t work if you’re trying to coordinate a microfrontend environment for example.
