Like what @DarkRuler2500 stated: DE has already added a feature to defense/interception missions where if the votes are unanimous, it instantly starts the next round(s).
Plus, if you can't do a mission solo, you should've extracted if you knew that. No need for someone to carry you. It was never a thing where if part of the squad wanted to stay, the whole squad is forced to stay. That's practically forcing all the players to stay on a sinking ship. So no, I'd rather not want that.
