Just because it seems intuitively consistent, or is there some practical
advantage - something that can only be expressed with these separate areas?
Separate sidewalk ways have advantages (you can properly connect other
ways and crossings to them, you can add tags such as surface, ...),
that's why I prefer them, too. Separate areas don't seem to let you
express any additional information, so I currently don't see a reason to
In fact, I think that a /single/ area:highway=* has an additional
advantage precisely if you map sidewalks and such as separate ways: it
becomes more feasible for applications to find out which sidewalk ways
belong to a highway because the highway and sidewalk ways are in the
same area:highway=* boundary. You wouldn't need relations or other
solutions to connect them.
