As discussed previously stream is defined by width and of course the 
width of a waterway can decrease along its course - both through actual 
water loss by evaporation/seepage (not relevant in Norway) as well as 
due to terrain (for example a waterway being relatively wide and 
shallow on a flat upland while becomming narrow and deep in a narrow 
valley further downstream).

And even if you'd change the definition of river/stream to represent 
importance this could never be locally verifiable and globally 
consistent at the same time.
