I've just found that length=* tag is quite closely connected to 
waterways (almost 72% uses):


Taginfo does not show such combination with rivers (it probably omits 
anything <1000 uses), but it's 446 lines already:


I'd like to add length=* as Additional tags/Useful combination in some 
Wiki articles, like:


I hope length combined with some simple classification (like 
order:classic=1) can be quite useful in case of low zoom rendering.
