I am afraid that "normal" GIS tools will always be lossy compared to the
structure of OSM. Almost all formats have a fixed number fields (except
maybe GeoJSON). I don't think you can reconcile that easily with OSM whose
richness is linked to the multiplicity of tags that we have.
So the lawyer=yes is a pain for "normal" gis, but at the same time very
powerful for the rest of us who feel limited by the number of fields that
you have in there. To some extent, osm2pgsql works like normal GIS, while
Osmosis produces a schema that keeps the spirit of OSM.
I think your something= is a good compromise in the end.
I don't think there is an easy answer here, and I really don't want to go
back to some limitations.
