I've been helping with the Windows issues in the GitHub repo but a few issues – actually most of those still open – haven't had any activity in a while. Some because I haven't gotten to investigating further, or debugging code, but some because whomever opened the issue, or others that observed or experienced the same issue, haven't followed-up or replied to questions or requests for more information.
For issues that aren't assigned to anyone, it would be sensible and reasonable to close them if there's no activity after some period of time, say 30 days or 60 days.
Or should I just 'flag' one of the core maintainers for issues I think warrant being closed because of inactivity?
