[nova][ptg] Can we close old bugs?

Hi, [This is a topic from the PTG etherpad [0]. As the PTG time is intentionally kept short, let's try to discuss it or even conclude it before the PTG] We have more than 800 open bugs in nova [1] and the oldest is 8 years old. Can we close old bugs? If yes, what would be the closing criteria? Age and status? Personally I would close every bug that is not updated in the last 3 years and not in INPROGRESS state.
