That just doesn't follow at all. You are claiming that having a tag for "no name" is a slippery slope which leads to a tag for "no special lane for tractors" or whatever. Why should that be? I don't think the slope is slippery at all. Names are unusual in this regard because there are certain classes of things which one expects to have them (such as roads) and, because of our mapping techniques using satellite tracing, there are often cases where roads are in but the names are not. Therefore, distinguishing between "definitely no name" and "name not discovered yet" is particularly important as a step towards completing the map without different people repeatedly visiting roads which turn out to definitely have no name. So having a "noname=yes" (or whatever - the syntax is unimportant for this discussion) absolutely does not mean you need a "nopostbox=yes" or a "notractorlane=yes" tag.
