iOS 7 notifications

I am seeing a lot of people posts concept of what iOS 7 should be but I am not sure if any one mentioned it. As an owner of multiple iOS devices and a Mac I would definitely like to see IOS notifications in the cloud.

- if I dismiss an iOS notification in one device it is dismissed elsewhere, lock screen or on the notifications bar.

- if I read an app that pushed the notifications I need notifications dismissed everywhere

- if I have an app on iPhone but not on my iPad I would still like to see notification on my iPad .. Dismissing it would dismiss it elsewhere,

- I can see all my active notifications from my devices on

Just like photo stream.

why isn't notifications on iCloud not the most important thing that anyone would want over any other flat UI designs?

Your thoughts?
