you'd be surprised how daunting it is for newbies to have to do install stuff from non-rpm originals. No matter how easy it is it's the psychological thing.
In my opinion shifting the two files teaches people how easy non-rpm stuff can be. If you are like me though, you need to put the files in the right locations for three or four different browsers. no sweat, but if you are a newbie, you might not know where to look for those plugin directories for each browser.
