Fully agree, VueJS is great! I always asked myself why someone would need different styles in just one component and not globally:

* Is there any special usecase for that kind of feature? I mean a button is a button and should always look the same (except maybe size and color)...

* Aren't components always looking the same way and a simple naming/clustering-strategy like BEM is enough to be flexible to change the style of some specific component?
