The neat thing about those items is that you’ll never get to them anyway. We sort our backlog by priority constantly, and all of the junk, old issues, or irrelevant bugs simply get shifted to the bottom over time, with more important stuff sorting itself up. Nevertheless, if I come across something I’ve documented before, I don’t need to file the same issue over and over again; if multiple customers request the same stupid thing over time, you’ll have a track record and maybe notice there’s a need for something; and finally, a long backlog gives lots of opportunities to onboard new people with long-standing, but minor issues.
