No, any open source project needs someone (or multiple people) triaging tickets; either keep them open and make sure they are implemented in a reasonable time, or close them as a 'wontfix'.
Of course, then you'll have the issue of people opening up new tickets for the same thing, and the triagers will have to either point them to the old ticket, or the discussion about whether or not to do it has to be restarted.
There’s just this thing called “reality” and unless your ticket by coincidence ends up catching the eye of someone who can actually do something about it, it will be left to rot. And because nobody will bother looking at the oldest ticket known to man™, the close-bot may as well close it. Tens of thousands of untriaged reports aren’t helping anyone.
As much as it pains me (I’m still tracking multiple bugs I reported) to say this, but all tickets with no activity for some reasonable time period must simply be closed. Things are _already_ out of control.
