I have never seen nice have any useful IO throttling effect (unless you are using 100% of your cpu with non-niced processes that is), so for exactly the reason you say, it takes very little cpu to do a massive amount of IO, so nice won't work. There are some kernel knobs that will control IO but those knobs are not very simple (see cgroups), so it is easier to just use the dirty, and a secondary effect to the dirty is that at 20%, the writecache can also cause the system to page to get that 20% memory.
