Allowing them to be displayed there and not having an active permission  
dialog would make it totally opaque to the application whether or not it  
can do system-wide notifications. This seems better for privacy and I also  
think it makes it less likely the user opts into something the user does  
not want.

This sounds somewhat better to me.

I'm still a little bit afraid of what's going to happen when we get many  
of these APIs that need some kind of user permission. It's going to be too  
confusing I think.
