There are a couple of such proposals in the wiki, see links at the bottom
of the discussed proposal. The purpose of relation is not only to state the
direction of a point feature, but also sometimes link it to the surrounding
features: for example, a direction of a sign is determined by the road
segment leading to it. Also, this is much easier for mappers and consumers
than to calculate degrees.
