Will this CL break existing library like Polymer?
Did you post "Intent to remove" mail to blink-dev?

A revert of this CL has been created in
https://codereview.chromium.org/212303005/ by vsevik@chromium.org.

The reason for reverting is: Breaks many browser tests:

Thank you for reverting.

I am now preparing the patch in the chromium side in
https://codereview.chromium.org/214093002/.
Let me re-land the patch in blink side after the patch in the chromium side is
landed.

We assumed that we've already announced that in "intent to ship Shadow DOM'
thread.
