@djakk all object are area but that don't make sens use it in database because data are an abstraction.
area is documented! highway are in model linestring but in other context it is as an area so highway area are forced with area=yes to map this object. there is no other solution to set an highway as a linstring because you can't easily have a good reprensentation with low level scale and can't map name correctly. But for micro mapping and set more realistic area (use in zoom level 19, 20 for representation) and data analyse there is an other model and you can join twice solution. It can be similar to interlis (suisse model) reprensetion based on data abstraction multilevel. Same data have multiple object type representation of your information with level scale definition. database is just a container and store an abstraction of information with a specific model. You can translate with same model or an other but there is a limitation corresponding to you abstraction level. an highway is also a 3D reprensation with concrete layers, kerb, and sidewalk... In other way you separete highway, cycleway, footway and other is there is a separator but this is the same global 3D object but you need use vector line and contrains for routing and it can use just in global polygon object. in this base you need use polygon and line solution. Other limitation is time cycle, number of contributors, resource materials.... and you will do choices to add udpated data in time.
