No particular reason other than that it is a fact that exists in the
world. In other words, we should be able to map whether or not the
ways do or do not share a bridge. As a consequence, users of OSM (e.g.
renderers) would be able to make better use of the data (e.g. to
render bridges).

What do you mean? If I don't know the width of the bridge, I can't draw it.
