@fbolduc mate.. I’ve just found out you suggested something like this earlier than me: Suggestion: Dockets for Custom Mission
Trust me, I didn’t try to rip off your idea or anything 
This thought had been haunting me for a while (“how can we have our custom mission games - but without being secluded into private lobbies at the same time”), so I’d been drafting the proposal for some time already. You were the first though, I admit that.
