Not very surprising, but almost none of these work on Firefox on my phone. I know it's Google, but adding a compatibility matrix before each feature would've been the least they could do.

I wonder how the web contacts thing is going to work on desktop browsers. I don't know anyone who still uses their address book on the desktop. I guess Chrome/Edge/Safari may implement an Gmail/Outlook/iCloud contacts picker?

That would mean updating the blog post every time any of the browsers starts supporting any of the discussed features. Probably better to defer to MDN or Caniuse, which are already good for that purpose.

Just noting that the browser support matrix is right here: https://web.dev/patterns/advanced-apps/contacts/#:~:text=con...

It's an Eleventy widget powered by MDN's browser-compat-data: https://github.com/mdn/browser-compat-data.
