If you're aware of the feature, it's not a privacy leak. If you aren't, it could be very damaging.

It would have been nice if the first time the Calendar parsed and sent emails on behalf of a user, it would ask if this is what they wanted. It doesn't have to bug them ever again, but that's a single instance of training that would minimize confusion.

Agreed. A simple confirmation popup is a quick fix which might prevent a lot of headaches.

Except that says: 'Who: This should begin with 'with' followed by a list of email addresses; these are added to the guest list.'

'Email [e-mail]' does not match this spec.
