Disabling clientside cheats on Tempus would probably hurt more than it would help, being able to see clipbrushes and use fullbright is super helpful on a large number of maps. Since the only thing it really seems to affect is runs on demo maps (Maybe a few soldier ones with long downpogos?). I would bet if the angle information came from the bcheck plugin instead of the little javascript thing people wouldn't really have much of a problem with it since the only complaints I've heard about angled bhopping are about how you have to use an external thing to get the information. Besides angled bhops are literally just another way to get a faster time, I remember people raging about bounces and ctaps ages ago because they were "cheating".
