Re: [whatwg/dom] Declarative Shadow DOM (#831)

On the HTTP header front...

`Feature-Policy` has been split into [Document Policy](https://w3c.github.io/webappsec-permissions-policy/document-policy.html) and [Permissions Policy](https://w3c.github.io/webappsec-permissions-policy/); `Document-Policy` is probably the better fit, for this use case.

After struggling with similar adoption-friction problems re: 3rd party Client-Hint delegation, a solution I have high hopes (and low expectations) for is [Origin-Policy](https://wicg.github.io/origin-policy/#origin-policy-well-known) (currently stagnant). Doing out-of-band opt-ins via a config file at a well-known URL seems possibly easier for folks than configuring HTTP headers.
