[webkit-dev] Position on emerging standard: Declarative Shadow DOM

[Mason Freed]

Hello WebKit,

I just wanted to send a final heads-up that Chromium is intending to ship
the Declarative Shadow DOM feature. We haven't heard much back from WebKit
in the last 5 months or so, but in the meantime there has been some good
discussion with Mozilla and the broader community. Several more performance
investigations have been performed, around the overhead of Shadow DOM
generally, and around the potential polyfill alternatives for DSD. You can
see a summary of these, plus all of the other changes that we've
incorporated, in this comment on the Mozilla Standards Position thread
<https://github.com/mozilla/standards-positions/issues/335#issuecomment-781697858>.
These changes are the result of your (and the community's) involvement and
feedback, so thanks. At this point, we believe all of the feedback has been
addressed.

Thanks,
Mason
