Hi Travis, I think this idea resonates well with the cross-origin use case / API change proposal we made two years ago [1]. In that proposal, we went a step further and tied custom elements with URLs so that those shadow DOM can be automatically instantiated by simply using those custom elements. e.g. if “like-button” element was defined in https://webkit.org/components.html, then we can use that component by simply "importing" the definition: <link rel=import href="https://webkit.org/components.html"; defines="like-button”> and using it in the same document (that imported components.html): <like-button data-url="https://build.webkit.org/";>Like build.webkit.org</like-button> We thought this model was more developer friendly than having each user of the component manually create shadow root. We also didn’t want to make component authors deal with situations like a shadow root being attached to an iframe, input, etc..
