It's risky. If you're light shielding and Marth sweetspots, you'll fall off the edge and be in a perfect position to be edgeguarded.You can use this to edgehog marth's if he's UB -> ledgegrab with fast fallers; shiek, cfalc, fox, falco are the ones I'm aware of, roll to the edge with your back to it and press Z, hold away from the stage and when marth Ub's he'll hit your shield and knock you onto the edge, make sure to let go of the control stick when you get hit or you won't grab the edge
It's also good for wasting your opponent's invul frames. Just run around and then jump above a platform and wavedash down onto it, and buffer a lightshield. If they hit you, you'll fall off the platform, and if they try to grab you you can just jump out.
Also the reason people use full is because you can't really shield grab with light shield lol
