When checked this morning, there were 119 PRs that haven't been updated in 30 days. The oldest was nearly 3 years old.
I propose the addition of a bot that will automatically close any PRs that haven't been updated in 30 days. The closing will act as a notification to the reviewers and submitter to evaluate if the work still has value, and just outright close work that is too out-dated for a straightforward merge. If the behaviour is done by a bot, it could reduce maintenance burden, and simplify the emotional response. A bot can link to a policy, and it feels neutral in its consistent tone.
