Well, the way that the Zen is phrased, it implies a bit more than 
that.  We all agree that there's a balance to be found between 
"completely flat" and "extremely nested"; the specific phrasing of the 
Zen conveys that (in the Python philosophy at least) the appropriate 
balance point is much closer to the "completely flat" side of things. 
    It's not "... as nested (or as flat) as you have to be and no 
more", it's "... as nested as you have to be and no more, but if you 
need significant nesting, you might want to re-examine your design".  ;)
