When doing this email trick I'd often broadcast the fact as I was "declaring email bankruptcy" to let others know I did this and may have missed their email. I've also lead many mass bug closures. Most stale bugs just need a ping or a friendly closure message. The cost to reverse a wrongly closed bug from a bug cleanup sweep is zero, and in the off chance it ignites interest in some other party still paying attention it at least signals intent and starts a conversation.
