The question I've come to conclude is this:

What harm does it do to the integrity of the map data?

The only harm is if there is no way as well, or if people start joing
roads to nature strips and making it a complete PITA to edit them
independently of each other in future.

At z18 the correct shape of the area will show if it's wider than the
way, and at other zoom levels the normal way will take precedent as
things get scaled etc.

As Roy said before routing software shouldn't try to route along
areas, at the same time the area should be rendered in such a way that
doesn't bleed colour. This could be done simply by tagging the area
the same as the way, or the more complicated method pre-processing
method David mentioned.

Also what ever is used should be tagged in such a way that people that
don't want areas showing can disable them from rendering, this way
everyone will be happy.

Also I'd only tag the way not the area with the name so that people
only wanting the way will still get things to render properly.
