And if not, the bug is probably not important. ¯\_(ツ)_/¯
At some point, you have to close things. Chances are they were spurious, have been fixed or made irrelevant (maybe the code no longer exists) or nobody cares.
And if someone does care and it's still an issue, you can reopen. It's not as if you are permanently deleting all the information for the rest of time.
At my last job, this was the attitude we eventually took with tickets that were several years old.
If it's still an issue with our internal customer [0], they can reopen the ticket or open a new one. But we've completely rearchitectured our systems since the ticket was first opened, our internal customer has changed leadership and has had considerable staff turnover, and not a single person has brought it up in our biweekly meetings with our internal customer for ages, so we might as well just close it out.
[0] when I say "customer", I'm talking about a department, not a single individual
