An use case for allow mapping barrier=block as asreas is a better
visualisation of a landcoverage. Mapping aeral objects as a nodes makes
the map a little bit lied.

Temat: Re: [OSM-talk] Barrier=block areas
Hedges can certainly be areas, some can be a few metres thick.
A common mapping scenario is a thick hedge and a stile at each side.
The only way to represent this is to map as an area and map the stiles
as nodes connected to the outline.

Barriers, by definition, provide some level of restriction. Without
attaching them in some form it becomes hard for routers to account for
them.
Hedges and walls are linear in nature, not an area.

Currently, barrier=block is not allowed to be mapped as an area. As
blocks can be big enough to map them as areas, I think it should be
allowed, the same as in barrier=wall or barrier=hedge. Anyway,
currently we have 3,9k of barrier=block areas in database.
