The existing > "length" tag would fit better, woudn't it? length vs. distance is only a wording issue. The tag just enables you to compare the geometric length with the lenght tag. If they are close (maybe within 5% of error) the river is mapped fine. As many length tags might have been taken from wikipedia (or wikidata) it is redundant as soon as you add a wikidata tag. see https://www.wikidata.org/wiki/Q584 (Rhine on Wikidata with its lenght 1232.7 km). Geometrical analyses of the river: 1160.34 km. Not a precics match, but close enought that no major parts of the river is missing.
