I like the idea someone mentioned in another thread that leveling when you reach 0 skill points should reward you with something like Guild Marks. In my head I was even thinking that the in-universe explanation for it would be like "Whoa, bro. You kept on fighting even when you were exhausted and were gaining nothing from it. We gotta give you props for that." or something.
Physical level surplus exists to show you that you need to work on your real physical level.
