Ability to dedicated host gameworlds?

What I mean by this is that I do try and host games very often, I have a good computer and good internet and when I do host nobody complains about lag (unless they live in Australia). Obviously it’s been stated multiple times they’re not going to let people do dedicated servers or such, but what about like the host can specify hosting like 500 matches as a spectator while they go do something else? Like while I go watch a movie in the living run I leave my computer running and host matches? Whenever your character dies in little crusaders you spectate the game.
