The point JK made that I was referring to was the server load from extra code multiplied by the number of times is simultaneously serving it up - even a couple of KO of code isn't going to make a big difference to a page load with an average connection, but if there are 100, 1000 people accessing a server, then it starts adding up to a significant additional load, for nothing (when it'd only take a minute or two to clean up most pages).
