By "consumer", we all think about "renderer" (which is in my knowledge the only consumer looking for bridges in OSM atm). If you keep the "bridge" tag on the multiple highways, it is duplicating the information. And you don't fix the rendering issue because Mapnik will continue to draw one bridge per highway. To avoid the duplicate rendering, we need the "bridge" tag only on the polygon. But then, the rendering software will have to decide to draw the polygon itself. Or like today, draw some symbols along the line. In both cases, if you want a correct rendering (draw only one bridge) wihtout simply drawing the bridge polygon, the software will need some spatial requests anyway (to determin the group of highway segments that belong to the same bridge).
