If the thought is to map a group of blocks as an area .. then my vote is
no at least without more information.
It raises the question as to what the level of obstruction is - are
motorcycles bared by this barrier? Horses? How badly are pedestrians
impeded? What about people in wheelchairs?
So there needs to be a scale of impediment.

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.
