This thread has prompted me to look at the ferry routes around the UK, and why only certain one are working. The biggest problems I have found, and so far fixed, are not the ferry routes themselves but the access within the ports. A lot of access roads have been tagged to prohibit access (private

Actually almost any proposal containing relations is criticised from this perspective (relations being too complex/complicated for mappers). You say someone has to do the coding, I disagree. It has already been done. JOSM with RelationToolbox plugin and, as Petr says, Merkaartor are handling

At the same time there are gates and the access is usually not free for everyone. So access=yes is in fact wrong in some cases. Something like access=customers (passengers of the ferry) might be the middle ground acceptable for both sides. Not knowing how different routers use access I believe

When you search wiki for grass, you get landuse=grass. When you type grass in JOSM's preset search box, you get landuse=grass. Potlatch does not offer any direct way to tag grass. landuse=grass was probably used before anyone thought about the difference between landuse and landcover (in osm

Nobody suggests that all information is immediately transferred to relations.But in this particular case where one real-world linear objects is represented by many OSM primitives (better yet if these primitives are common for more objects), relations seem to be the clearly right way to go.
