Currently "Clean Event Messages" deletes both the event start message AND the original event embed.
I would like an option to only delete the event start messages.
This was originally my suggestion. Back then, custom notifications did not exist. I would like to change this so the event creation messages are saved (the message with the original details & RSVPers) but all the notifications and event start messages are deleted. The reasoning is having a channel with the history of events and their attendance indicates server life, while a mess of old event start and reminder messages could mean anything. Separating the notifications from event creation into different channels seems excessive, and "backreading" an events channel to see the previous events is more intuitive.
