Put differently, "percentage used" possibly is a rather imprecise, abstract, questionably useful value which harddisk firmware would actually derive internally as a "magic" calculation from certain memory-behaviour attributes, so vendors probably figure that it's better to instead publish exact attributes with a specific meaning, from which then some kind of "percentage used" value can be more or less "magically" calculated, *externally* (and with easily downloadable calculation updates in case it turns out that prior calculation was imprecise for that device type).
