Unless I misunderstand the wiki page, whitewater:section_grade is only documented as applying to waterway=river. There is nothing there implying it is valid to use it with anything other than rivers. Whereas route=* applies to any route which isn't rigidly defined: boat travel, aeroplanes, driving across a desert. Anywhere you need to join points A and B with a way that is not rigidly defined but merely a suggestion. Yes, you could modify the documentation so whitewater:section_grade also applies to lakes, oceans and seas but then you'd need to emphasise that grades higher than 0 must not be used on anything other than rivers. And it still doesn't apply to aircraft or driving across a desert or pistes. You're trying to bash a square peg into a round hole here, and doing so when somebody has already handed you a round peg of the correct size. -- Paul
