Since I posted this, there have been some changes made to the new app creation flow to better support the two products (Crash Reporting & Pulse). As part of that we've taken away some of the notification options - this was a mistake, and we're looking at re-adding them now.
Our first thought is to have the option for you to get notifications (I suspect that's a fair default), with another option to turn on notifications for the rest of the team.
Further to this, we're looking at ways to add meta data to the emails so that the 'unsubscribe' link appears in Gmail so you can one-click remove yourself from notifications if you are getting some you don't want in future.
Sorry that this thread is a bit out of date. We'll be looking to get this change out in the coming weeks as it is frustrating sorry.
