Anytime you see someone on HN lamenting that Safari is the new IE because it doesn't implement something, 99.9% of the time it's Chrome-only non-standards.

- All of hardware standards. WebHID's timeline is especially egregious https://github.com/mozilla/standards-positions/issues/459#is...

- Most of standards advertised on web.dev as "new exciting opportunities you can try now". E.g. WebTransport https://developer.chrome.com/docs/capabilities/web-apis/webt.... The status of that spec is "scribbled on a napkin", but somehow already released in Chrome.

- Other "standards" and "specs" here and there like web share target https://w3c.github.io/web-share-target/
