Web Components code should be fully behind a feature flag like all other experimental features. Platforms that are not interested in this feature shouldn't need to take the performance and binary size hit from it. Also it is not ok to make other parts of WebKit internals depend on experimental features. The original implementation of <details> did not have such dependency.

The feature define should be renamed to WEB_COMPONENTS or similar. SHADOW_DOM is a bad name as we have tons of internal shadow DOMs that don't depend on most of this code.
