Usually with 200 or so values there is some categorization of values that exists - maybe it's counties in a state that can be divided into regions or songs by an artist that can be divided into album or period. Large multi-selects seem to necessitate a multi-step selection process where the user can drill down (All of this category, none of this one and some of this other one - specifically this, this, not this and that). I think it's feasible for such a tag proposal to make its way through various working groups but it'd be pretty opinionated and we'd likely end up dividing multi-select inputs into several different classes (which would probably be a good thing).
