Antti and I have successfully implemented new slot-based shadow DOM
API, and it has been enabled on Safari Technology Preview as well as
Safari 10 included in macOS Sierra. There are a few remaining bugs to
be fixed as tracked in webkit.org/b/148695 but we believe we've
polished it enough to be shipped on all ports soon.
As such, we're enabling the feature and removing the build flag on all
ports on webkit.org/b/158738. We still have a runtime flag so please
disable the feature using that if you're about to ship a product with
WebKit and would like to disable the feature on your port.
