Recently someone told me that addresses are not important for POIs,
and perhaps he was right.
Suppose I want to navigate to a particular shop in that mall. I tell
the router I need to go to that shop. If the point of that shop is
properly mapped and all footways from the parking and indoor corridors
are mapped, the router should be able to take me there. Does it matter
that the POI has an address, or that it is put on the building,
perhaps not, as long as its coordinate are correct.

OTOH, when one of my friends lives in a large apartment building
complex, I do only have an address. So perhaps the building has
multiple entrances, which are marked with different house numbers,
groups of flat numbers, or something else. In that case, I want to be
able to navigate to the correct entrance. For that, the navigation
software needs to bring me to the correct entrance. Unlike malls,
apartment buildings often require you to choose the right entrance and
you cannot go from one part of the building to the other. So here the
address(es) should go on the entrances.

Furthermore if I want to send a mail (paper-type) to a shop, it is
interesting to know its correct address, and having only a general
address on the building does not help.

So yes, different usage might require different mapping.
