I would guess that searching through github profiles to decide how good someone is would probably take a while. Without understanding the context of the code it always takes some time for me to tell the actualy quality of it. Also some of the best engineers I've met haven't had much work in public on github. I think these sorts of gimmicky tests while terrible exist mainly because they are a one size fits all solution that doesn't take too much work and will filter out the really bad applicants.
