I don't believe we can remove webcomponents that easily.

Many tests are testing behavior that requires the polyfills to be loaded too.
Those tests likely have an HTML file that contains a script tag to load the .js
polyfills and the extra hooks for dart2js (search for 
`packages/web_components/webcomponents.js` and
`packages/web_components/dart_support.js`)
