Notifications can't be deleted

Why can't we delete notifications? I still have a notification that I need to confirm my email address... I did that.. Got it.. go away.. When I get a response to a comment, I need to be able to delete the notification.

Ultimately, I would like to control when I get notifications but at a minimum I need to be able to delete them. I would like to have a trashcan so I can go look in it if I accidently deleted something. The trashcan would automatically roll items out of it after X number of days...

Not sure what others think...
