Ilya, please don't use the word "subjective" for this. Subjective tagging has no place in OSM because it is not verifiable; we don't want that and we shouldn't let people think we do.
What you seem to propose does however not look "subjective" since you are keying your suggested tags to the length of the river, so they are verifiable (and if two people don't agree then there is one "correct" way to do it, not "two differing opinions"). I do see an issue with using the length as a decision making property because it is not something you can necessarily "see" from aerial imagery (or if you are actually at the location) - you need external sources to determine the length. (Sometimes two rivers merge and you cannot really say which one continues and which one ends - it is kind of arbitrary but at least it is recorded somewhere and known.)
