[OSM-talk] highway=* + area=yes vs area:highway=*

[Darafei "Komяpa" Praliaskouski]

area:highway= to highway= is what waterway=riverbank to waterway=river.

The first is area used to understand the curvature of the edge, the second
is a routable way. They denote different things and aren't interchangeable.

As with rivers, it's expected that lines are mapped first, and on top of
those detailed polygons are overlaid later.
