What's to stop players from intentionally getting booted when they're at a slight disadvantage or don't like the picks they ended up with, hoping they can pressure the other player(s) into a rematch, saying "But it was still anyone's game!"
This is mostly why we're probably going to decide on not allowing any games to be replayed after pick stage when we write the official ruleset. We don't want people to take advantage of others' kindness or to drag out the season by intentionally getting booted.
