As you and many others frequently remind us: OSM is first and foremost
about the data and not any specific use-case or rendering thereof.
Yes - but a data model is not a neutral representation of reality: it is
a projection through a use-case, mapping reality to a construct fit for
specific purposes. In the relational database world, we cannot produce a
satisfactory schema without knowledge of what sort of queries are
intended. Flattening the highly dimensional reality into any data model
involves such choices. Closer to the daily preoccupations of
Openstreetmap, even lists of attribute values are reductionist and
finding the appropriate tradeoff cannot be achieved isolatedly: it
requires input from those who will deal with the consequences of the
choices - the data-consuming users.
