Re: [webcomponents] Disallow attachShadow(...) for some elements. (#110)

Given that the list of HTML elements is finite, a safelist vs. a blocklist is equivalent except for future changes to HTML. I would assume any future changes to HTML would coordinate with the shadow DOM spec, especially if we take the approach in https://github.com/whatwg/html/pull/131 (or the safelist equivalent). So I think debating safelist vs. blocklist is not interesting. You should just come up with the list, in either form :).
