In many cases I believe that renderers *should* render such "virtual" paths.

Routers and human readers have the same problem:
If e.g., a paths stops and there is just a few meters to the road, there is no way to 
know, using only OSM, for neither humans or machines what is in between or if it is 
possible to navigate from the path to the road.

Even on squares it is helpful to see natural paths.
