should be removed, and the linked page should be either deleted or marked as deprecated in some way.

What did you expect to see?

No mention of the document-domain feature policy

Do you have any supporting links, references, or citations?

The feature policy is being removed from the spec in https://github.com/whatwg/html/pull/8549 and from Chromium in https://chromium-review.googlesource.com/c/3930823 .

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Feature-Policy/document-domain says that document-domain feature policy was enabled in Chromium 77, but I believe this is incorrect; @otherdaniel says it was never enabled by default.

Do you have anything more you want to share?

No response

https://chromestatus.com/feature/5341992867332096 seems to indicate that it did ship in Chrome 77, but I'm not sure if there is some subtlety in these notes that I am missing.

If it did ship, our usual policy is to keep docs for 2 years after it unshipped.
