For Context support, I think the reason it's not supported is because Server and Client components have different lifetime. In theory they could add something like Server Context, that's accessible only to Server components. For CSS-in-JS, those are all 3rd party libraries, so they need to adapt on their side. For example, `styled-components` uses Context heavily, so they need to re-think their approach. For `css-modules` adapting to Server components looks doable, but requires substantial amount of work.
