For better understanding: What the proposal tries to specify is an 
importance rating for rivers based on their name, i.e. the Garonne 
would by definition have the same rating everywhere it is named 
Garonne.  If the upper part of a river is named differently than the 
lower part it would be a different river - hence potentially a 
different importance rating (like Nile - Blue Nile/White Nile or 
Rhein - Vorderrhein/Hinterrhein).

This has very little to do with the size of a river as a local property 
(like the width or the discharge) which a mapper would normally use as 
a basis for tagging the size of a river.
