Mapping the path of a highway as a 'way' is a generalization. This can
be extended by adding additional tags to describe all the fine detail
such as width, number of lanes, associated cycle and footpaths, and so
on, but this is a simplification to the actual fine detail. I'll repeat
what I said, 'highway' SHOULD only be attached to a way and not to areas
so that we have the simplification for lower resolutions of the data.
ADDING areas to map the fine detail that is associated with the
information also contained in the additional tags should be tagged by
association and not by adding additional 'highway' tags to the areas. IN
THAT CASE area=yes could be used to identify that there are associated
area objects that can be used on higher resolution mapping. I don't
think 'area:highway=' has place especially where the 'centerline' way is
used to combine several highway=xxx types such as road,cycleway and
footpath ...
