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?
Raises hand.
But I don't use gmail, chrome or Edge. The mac desktop contact manager is integrated into calendar, messaging, mail etc and all that is true on ios. I use a third party calendar and used to use a third party desktop address book and integration is perfect.
Clearly these are internet apps but not web apps. I can't see how web would add any value, just friction.
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.
