Hello,
https://fedoraproject.org/wiki/BugZappers/HouseKeeping should certainly be in https://fedoraproject.org/wiki/PackageMaintainers/Policy currently it is very hard to find. Maybe it should be rerwrited to be presented as a policy, but currently putting it in Policy should be better than the current situation.
And also I didn't found anything on this page telling that EOL version bugs are automatically closed although I think that it is the case.
