Even though the bridges were not the best example, I would not dismiss their importance. Maybe a better example is when two roads (numbers) run on the same asphalt. It is not uncommon in my country and probably possible elsewhere.
There is support for this - that is JOSM + RelationToolbox plugin. Potlatch recently gained the ability to highlight all relations, which is great. I will try using it for a while and suggest concrete improvements on this matter. There were concerns if it is more gain for mappers or for data consumers. I am the former and use the later. As a mapper I prefer one thing being present on one and only one place. I prefer one real object being represented by one osm object be it point a way or a relation. As a mapper I hate repetitive work and relations let me get rid of it for some part. I like to know that I have made no mistakes - relations are easier to check than 50 way segments. If the whole street gets a different surface or gets wider, relation at least gives me an easy way to select all members. I like relations when mapping. As a user of osm applications I want them to be as feature rich as possible. Frederick is right that consumers would not go away because data model is not perfect. But they might omit a feature or ten. I started contributing because osm maps were more detailed and precise than any other. Therefore I believe that the better map comes with osm watermark the more contributors the project gains.
