Yes. Unless he adds them later (like feature suggestions file)
Still, no double evaluation.
I don't think his purpose is to implement a feature suggestion. It's to allow users to create new "commands" (in real time) which cause his bot to respond appropriately. Writing new events to a file is not the way to go about this. If you're writing user input to loaded scripts you've just compromised your system.
