Firstly note that routing across areas is (theoretically) much harder than
routing along ways (Non-polynomial time VS polynomial time).

Secondly note that the problem is not restricted to pedestrian routing, e.g.
parking areas. There have been cases where people mapped the road surface as
areas, although they would then also have ways running down the centerline.

Supporting areas is on my list of things that I would like to do, but there
are many other things in front of it. I recently added dragable routes to
the Osm.org Routing Demo. I improved the endpoints. Negotiated for a better
server. Routing instructions and translations. And for Christmas I want a
mobile application for large scale collection of house numbers.
