I've been developing Facebook Connect applications for a long time, and I'm wondering - hasn't facebook had this feature already for email addresses? One of the permissions read: "Send me email" (optional: send through a facebook proxy) So now, you can also let the apps know phone number through the graph? I don't find that too big of a step.

That is, thankfully your friend can't decide they want to share there contact information with some app and vicariously share yours too.
Big difference.
