https://github.com/whatwg/html/pull/5465 https://github.com/w3ctag/design-reviews/issues/494 A declarative API to allow the creation of #shadowroot's using only HTML and no Javascript. Since this is a parser-only feature, parsed DOM content will contain only "normal" #shadowroot nodes. Devtools already fully supports Shadow DOM, and all of those existing tools will continue to apply to this new method of declaratively creating Shadow DOM.

...chromestatus seems to have left off the requested Origin Trial Experiment Timeline, which should be: M85-M87.

Thanks,
Mason

Unnecessary LGTM2!

Do you have partners lined up to experiment with the API? Did you already gather developer feedback from playing around with it behind a flag?

Thanks everyone. Yoav, I do have two partners roughly lined up to experiment. And I have spoken to at least one developer who has tested out the feature using the flag. No red flags yet. I could always use more feedback!

Thanks,
Mason
