I don't know if there have been any thoughts around on this, but I think there is no form of policy in place regarding the CentOS bug-tracker? I'm thinking along stuff like i.e. no activity for > 1 year --> close issue.
I would like to hear feedback (suggestions if there are some) on this thought. If we want to move something like that into place (and there is enough feedback), i'd be willing to write an initial draft to expand upon.
Thanks and Cheers Christoph
