*I wish to amend the Wiki to explain that destination_sign relations can also be used for pedestrian and indoor routing, not just at "crossroads". Does that require opening a discussion in the discussion page, or may I just go ahead ?*
I think you're reading too much into the single word "crossroads" in the introduction. Perhaps the simplest solution is simply to add an explanation along these lines: "A crossroads for purposes of this tag is the intersection of two or more highways, including pedestrian ways, cycleways, etc." Although personally I think that's already implied.
