I think that --add-pois-to-areas only makes sense for open areas that can
be accessed from all directions.  For example, supermarkets usually have
one or two entrances, and the auto-generated POI could produce wrong results.

Here is a real-life example: A shop that is in a fenced area.  When I first
visited it with the navigator, there was no POI, but I selected the building
on the map and asked for a (bicycle) route.  It almost got me there, but
it told me to go through the fence.  I had to make a non-trivial detour to
get to the entrance.

Thus, I would say that it makes sense to manually create POIs for all areas,
at the entrance.  Or, if --add-pois-to-areas is to be made the default, it
should not add duplicate POIs if there already is a POI nearby with the same

Please, if you can implement the above suggestion (avoiding duplicate POIs),
it would be more useful.  (Sorry if it already does that; I have never used
the feature.)
