Notes

Standard support includes the HTTP Feature-Policy header, allow attribute on iframes and the document.featurePolicy JS API.

Older Chromium browsers did not support the JS API.
Safari and Firefox only supports the allow attribute on iframes.
Safari doesn't support a list of origins or a wildcard.
At least partially supports Permissions Policy, the main replacement for this spec.
