I think in bicycle-OSM we have kind of an tacitly agreed approach: bicycle
lanes (divided from motorised traffic by a painted line) are generally
mapped on the road way whereas separate parallel cycleways are tagged
either on the road way or as separate way, with the former often being the
first, fast mapping and the latter being considered the more advanced
