Ok, after some more discussion on #osm-it at oftc , we kind-of-agreed that
route=road isn't suitable for all cases, and there are places in the world
where it's not suitable at all (because not all streets with the same name are
proper "routes").

So we settled that Relation:street, as proposed in [0], would be more suitable,
both for grouping segments together (yes Simone and Nathan, just for the sake
of it, because I think it's convenient to keep them logically together with a
relation), _AND_ for grouping a way with its housenumbers.

This would obviously deprecate Relation:associatedStreet in favour of
Relation:street.
