At a previous job we practiced aggressive, automated ticket de-prioritization. Every N days of inactivity, a ticket would drop one priority point (and I think higher priority tickets were de-prioritized at a higher rate). The theory was that anything that was truly high priority would have been done. In other words, things that we left on the queue were actually lower priority than marked. Given our extremely limited developer-hours, it was important to stay focused on the things that actually mattered.
