The AOS fails due to a plastic part being exposed to heat cycles and oil vapor. Over time, they get brittle and crap out. Altering the rate vacuum levels develop might slow that process very slightly, but it would not prevent it, and I would be more concerned about what the rings are doing while the vacuum is low. As I noted above, restricting vacuum will slow down but not stop the development of maximum vacuum in the system.
