   Project mention: Helium Browser | news.ycombinator.com | 2025-09-24

   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/

   Can I Use had to create a special UNOFF tag for all the web APIs that Chrome (mostly Chrome) ships. If you go to MDN and look at all APIs marked as "experimental", you'll find that most of them are already shipped in Chrome: https://developer.mozilla.org/en-US/docs/Web/API
