I don’t think so. It should have an easy way of reopening - if it has, and you’re flooded with tickets on an open source project that you can’t possibly handle all, then it’s a good way to prioritize. Of course it doesn’t have an easy way to reopen here, which sucks, it’s some kind of locking instead of just closing it with a possibility to reopen.
Old tickets have a non-zero chance of the reporter being the only one to run into it because of a weird setup/usecase (and then abandoning the project), it being fixed by other work, or probably a bunch of other reasons it could be obsolete.
If no one cares enough to reopen it once every 6 months, then it’s probably fine to ignore it indefinitely.
But yeah, that’s the thing, it doesn’t matter where it is based when there can’t be any information gleamed from it.
