The 'river-bank' approach has been exceptionally useful to me at times
when trying to micro-navigate. Why would it ever be better to have less
information?
This is not an either-or decision; many people map riverbanks for
appearance plus a waterway=river way through the centre. Among other
things, this gives one the chance to map the direction of water flow.
(In theory, such a line could be computed but that's something of a
black art; http://ageoguy.blogspot.com/2010/12/squelettisation.html for
interesting details - and I sure as hell don't want to have to set up a
machine to do that for the whole planet on a daily basis...)
