Doable for sure but an awfully bad idea, mapping bays as areas would
mean two features for the same object (coastline polygon and bay area).
Furthermore the outer edge of a bay, i.e. the edge that is not
coastline is usually not well defined and would require an arbitrary
Maintaining bay polygons would be an awful mess, they would end up
frequently being broken. And there is no gain at all in terms of
substantial information in the database compared to nodes (since the
coastline is already mapped and the non-coastline edge is arbitrary).
The reason you would prefer areas is probably simply that this would
make it easier for to use in rendering - but making life more difficult
for the mapper just to make it easier for the renderer is not a good
idea. Based on the coastlines and the bay nodes you can quite easily
generate approximate bay polygons that can be used for the purpose of
labeling for example (yes, even for the Paulsdorfer Bucht).
This argument by the way was already made in a slightly different
