If each level is averaging 10x the previous level, then all 3 levels will only be 11% bigger, or 211MB.
You *really* want to get *all* the warnings - quite often, you'll be looking at a set of 15 or 20 level-3 warnings. And if you had the Level-2's in there as well, you'd immediately realize that the single level-2 was the real root-cause of all the cascating warnings.
Also, having it as a "volume control" means I don't have to go reading the Makefile to figure out which number I need to specify for which message - I can just say W=3 and *know* the flavor I want will be in there somewhere. Let's face it, if there's over 10 or 15 warnings involved, grep or your editor's "locate next" will do a better job of finding it than you ever can...
