Re: [w3c/webcomponents] Generic programs can't reliably use/manipulate documents via the DOM (#640)

> does it cause problems for you that you can't access built-in element's shadow DOM? If not, then why is it a problem for custom elements

@matthewp built-in elements' behaviours and properties are comprehensive, well-defined, and easy-to-find. There are occasional limitations (e.g. setting the cursor position in an `<input type="date" />`), but nearly everything you might want to do with them is possible.

By contrast, custom elements need not have any useful/relevant behaviours and properties. Even when they do, code that isn't written for them has no reliable way of using them, since it can't "read the documentation".
