On WN it is supposed to be the preboarder and one assistant. Whether that happens is up to the GA. I've had it happen both ways.
Delta also allows everyone on the PNR to preboard. It can be a big deal with bin space when it's a group that is carrying on everything but the kitchen sink and you have a gate agent that doesn't enforce the carry on limit or you have a flight attendant that doesn't say anything when they throw their stuff in the first FC or C+ bin they come to because they don't want to carry the stuff to the bin above their seat. Especially in cases where the gate agent doesn't clear the upgrade list until the middle of boarding.
