Just because it's been around a long time doesn't make it less relevant. If this is a "long-standing issue" and "known bug," then the complaint shouldn't just go away, but become "why isn't this fixed yet?" I know the developers have plenty of posts on new bugs to sort through too, but, old or not, it still needs fixing, and if people complain about the same bug over and over again, it might annoy a developer enough to get it fixed.
