Re: [w3c/webcomponents] Provide a lightweight mechanism to add styles to a custom element (#468)

All of my [custom elements](https://github.com/trusktr/infamous) except for one, have styles but no shadow roots and do not distribute any children. Currently I'm applying styles using [JSS](https://github.com/cssinjs/jss) directly to all of their `style=""` attributes (because otherwise they don't reach into shadow roots).

Applying these styles via the custom element definition would be great!
