Why is that? Have you used it for significant projects? I've found the hierarchy of CSS classes and where they're defined (e.g. global or component) become hard to to manage and refactor when you want to reshuffle components around... I feel postcss-based styling is simply more predictable and easier to refactor. And the abstraction, which can be clunky at first, becomes a sort of intuitive DSL which let's you develop faster...
