Mozilla would like to see more real world uses cases of Declarative Shadow DOM in the wild. GitHub has confirmed that they are using DSD and see many architectural benefits from it, especially for their design system. Although a polyfill exists, it comes as a bit of a catch-22 when trying to target pure SSR Web Components (HTML) use cases.
