One of the questions for passing scoped classes to a component is why you want to do it. If you have complex selectors, it would effect the implementation of the component, so I think that would be an anti-pattern. Just modifying the root would be great, but in Svelte I believe one component can translate to multiple root nodes, so all of them would need to get the styles, which again would increase the coupling between the component usage and implementation. I think there's just no clean way to do what you want.
