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.
