It would be very handy to have a global feature where everybody on a proof is removed when a new version is created. Many times I am left on a proof when I don't need to be, and this not only clutters my dashboard, but wastes a lot of my valuable time reviewing something that I don't need to simply because somebody couldn't be bothered to remove me from proof when they should have.
By having to add proof recipients back on, people are forced to think about efficiency in their proofing workflow and only add the people they need to.
