Yes, HoloID and HoloStars as well
Actually yes!! But it will be a long time before this become available. Also, I can say that this will not be available at your first gameplay when it's available- since there will be not only random maps, but also scenarios and other gamemodes, this will be a feature unlocked. Not sure if I will do a level system for this, achievement, etc. But again, I can't say when this will be available.
